1. 1.what are some possible lengths of each side of the triangle is isosceles?2.what are some possible lengths of each side if the triangle is scalene?tolong jawab ya kakak adik
Jawaban:
1. The triangle is formed by 3 vertices whose positions are not in line connected.
In each triangle, several properties apply, including;
the sum of the lengths of the two sides is always greater than the side lengths of the triangle;
the sum of the angles of a triangle is 180 degrees;
the largest corner is the corner facing the longest side, while the smallest corner is the corner facing the shortest side;
the size of the outer corner is equal to the sum of the two corners that are not aligned with the outer corner.
2. that the sum of the lengths of each of the two sides of the triangle must be greater than or equal to the length of the third side.

yg ditinjau dari PanjangSisi-sisinya.
Jawaban:
A. Obtuse triangles
Langkah langkah :
Pertanyaan :
There are types of triangles based on the side except :
Artinya :
Ada jenis jenis segitiga berdasarkan sisinya kecuali :
Pilihan jawaban :
A. Obtuse triangle = segitiga
tumpul
B. Equilateral triangle = segitiga
sama sisi
C. Isosceles triangle = segitiga
sama kaki
D. Scalene triangle = segitiga
sembarang
Penjelasan :
Menurut jenis sisinya, segitiga dibagi menjadi 3 jenis
1. Segitiga sama sisi = ketiga sisi
nya sama panjang dan ketiga
sudutnya sama besar
2. Segitiga sama kaki = Hanya
memiliki 2 sisi sama panjang
dan 2 sudut sama besar.
3. Segitiga sembarang =
segitiga yang masing masing
sisinya tidak sama panjang
dan masing masing sudutnya
tidak sama besar.
Sedangkan segitiga sembarang (scalene triangle) merupakan segitiga berdasarkan jenis sudutnya.
Jadi, jawaban yang tepat untuk pertanyaan diatas adalah
= A. Obtuse triangle

5. in an isosceles triangle,one angle is three times the size of the other two angles. Work out the size of each angle.
Jawab:
Penjelasan dengan langkah-langkah:
Penjelasan dengan langkah-langkah:
total angles in a triangle is 180.
one angle is three times the size of the other two angles.
so:
x + x + 3x = 180
5x = 180
x = 36 degrees (size of each base angles)
one angle is three times the size of the other two angles
first angle: 36
second angle: 36
third angle: 3 × 36 = 108

7. ##Quiz #106 ##• english version• big point• no spam==========A right triangle has side lengths of 4.5 cm, 6 cm and 7.5 cm, respectively.find the length of the radius of the inner circle and the radius of the outer circle!
Jawaban:
•The length of the radius of the inner circle is 1,5 cm
•The length of the radius of the outer circle is 3,75 cm
Penjelasan dengan langkah-langkah:
Known:
a=4,5 cm
b=6 cm
c=7,5 cm
s=½(a+b+c) = ½(4,5+6+7,5)=½(18)=9 cm
L = √s(s-a)(s-b)(s-c) = √9(9-4,5)(9-6(9-7,5) = √182,25 = 13,5 cm²
The length of the radius of the inner circle (r):
[tex]r = \frac{L}{s} \\ r = \frac{13,5}{9} \\ r = 1,5 \: cm[/tex]
The length of the radius of the outer circle (R):
[tex]R = \frac{abc}{4L} \\ R = \frac{4,5 \times 6 \times 7,5}{4 \times 13,5} \\ R = \frac{202,5}{54} \\ R =3,75 \: \: cm[/tex]

9. 1.) Triangle MNO is a right-angled triangle and triangle NOP is an isosceles triangle. MO is perpendicular to OP. ∠OMN = 53°. Find ∠OPN.
Penjelasan dengan langkah-langkah:
< MON = 90-53= 37°
< NOP = 90-37= 53° = < PNO
=> <OPN=180-(53+53)
=180-106=74°

11. a pyramid,the base has an isosceles triangle form with sides of 10 cm,10 cm and 12 cm.if the height of the pyramid is 15 cm,then calculate the volume of pyramis
tinggi segitiga sama kaki :
(1/2 sisi alas)² + tinggi ² = sisi miring²
6² + t² = 10²
t² = 100-36
t = √64 = 8 cm.
Maka, volume limas :
V = 1/3 (Luas alas segitiga) X tinggi limas
= 1/3 . 1/2 . alas . tinggi . t limas
= 1/3 . 1/2 . 12 . 8 . 15
= 240 cm³
12. The base of an isosceles triangle measures 24 cm.and it's area is 192cm2.find it's height
Jawab:
Penjelasan dengan langkah-langkah:
192cm²=1/2.24cm.h
192cm²=12cm.h
h=192cm²/12cm
h=16cm
So the height is 16cm

13. (4) EFG is a right-angled triangle. EFH is a straight line. FHJ is an isosceles triangle. Find LGFJ. J 52° G H 78° F E
segitiga
∆FHJ sama kaki
∠JFH = ∠JHF = (180° - ∠FJH)/2
∠JFH = (180° - 52°)/2 = 64°
∠GEF + ∠GFE = 90°
78° + ∠GFE = 90°
∠GFE = 90° - 78° = 12°
∠GFJ
= 180° - ∠GFE - ∠JFH
= 180° - 12° - 64°
= 104°

15. Ariel completed the work below to show that a triangle with side lengths of 9, 15, 12 does not form a right triangle
Jawaban:
Ariel menyelesaikan pekerjaan di bawah ini untuk menunjukkan bahwa segitiga dengan panjang sisi 9, 15, 12 tidak membentuk segitiga siku-siku
Dengan berdasarkan teorama pythagoras kita bisa menentukan jenis segitiga.
Untuk menentukan sebuah segitiga harus memenuhi syarat yaitu → a + b > c
Menentukan jenis segitiga
Dalam Δ ABC, apabila a, b, dan c adalah sisi-sisi di hadapan sudut A, B, dan C, maka berlaku kebalikan teorama Pythagoras, yaitu :
- Jika a² = b² + c² , maka Δ ABC adalah segitiga siku-siku di ∠ A
- Jika a² < b² + c² , maka Δ ABC adalah segitiga lancip di ∠ A
Sisi a terletak dihadapan ∠ A
- Jika b² < a² + c², maka Δ ABC adalah segitiga lancip di ∠ B
Sisi b terletak di hadapan ∠ B
- Jika a² > b² + c², maka Δ ABC adalah segitiga tumpul di ∠ A
Sisi a terletak di hadapan ∠ A

16. A triangle can be formed having side lengths 4, 5 and 8. It is impossible, however, to construct a triangle with side lengths 4, 5 and 9. Ron has eight sticks, each having an integer length. He observes that he cannot form a triangle using any three of these sticks as side lengths. The shortest possible length of the longest of the eight sticks is
Penjelasan dengan langkah-langkah:
Let two sticks be size 1. The third stick must have length ≥ 1 + 1 = 2. So choose it to be
length 2.
Choose the stick of length 1 and 2. The fourth stick has to have length greater than the
maximum possible sum of the other sticks, i.e. it must be ≥ 1 + 2 = 3, so it has length 3.
The fifth then must be of length ≥ 2 + 3 = 5, so it has length 5.
The pattern used to generate the next stick is obvious - this is just the Fibonacci sequence
{1, 1, 2, 3, 5, 8, 13, 21, . . . }. The eighth term in this sequence is the longest stick, which
is 21.
Therefore the longest stick length is 21.
17. The perimeter of an isosceles triangle is 36 cm. If the base is 10 cm, the area of the triangle is .... cm2. (Pythagorean Theorem)
Penjelasan dengan langkah-langkah:
½ kali 10 kali 36 =
10 kali 36 : 2 =
360 : 2 = 180 cm²
maaf kalo salah ^_^
Pythagorean Theorem"In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides".
Question:
The perimeter of an isosceles triangle is 36 cm. If the base is 10 cm of length, the area of the triangle is ... cm²
Step by step:
Isosceles triangle have 36 cm of its perimeter. The perimeter of triangle is calculated by sum of each side.
Finding length of each leg (x):
36 cm = 10 + x + x
36 = 10 + 2x
26 = 2x
x = 13 cm.
To find the height of triangle, use pythagorean theorem. Let height is written by "y".
[tex]\displaystyle\\y = \sqrt{13^2 - 5^2}\\\\y = \sqrt{169 - 25}\\\\y = \sqrt{144}\\\\y = 12~\text{cm}[/tex]
Calculate the area:
[tex]\text{Area of triangle:}\\\\\boxed{\frac{\text{base}\times\text{height}}{2}}[/tex]
[tex]\displaystyle= \frac{10 \times 12}{2}\\\\= \frac{120}{2}\\\\= 60~\text{cm}^2[/tex]
Conclusion:
The area of an isosceles triangle with 10 cm length of base and 36 cm of its perimeter is 60 cm²

20. The lenght of the legs of an isosceles triangle is 4 meters more than its base. If the perimeter of the triangle is 44 meter. Determine the lenghts of the sides of the triangle!bantuin plisss
Jawaban:
4meter x 44meter = 176 meter
Penjelasan dengan langkah-langkah:
Sisi x sisi x sisi
Isosceles triangle = segitiga sama kaki.parimeter = keliling
k= 44m..
kaki nya = 4cm lebih dari sisi bawah.
caranya
K = a + b + c
44 = (4+x) + (4+x) + x
44 = 8 + 3x
44-8 = 3x
36 = 3x
x = 36/3
x = 12
berarti sisi nya =
kaki = 12+ 4 = 16m
sisi bawah = 12m
ini ya kak jawabannya ..
