Question

5. If the angles of a triangle are in the ratio 1:2:1, find all the angles of the triang
Classify the triangle in two different ways.​

Answer 1

Answer:

1. let angles of this triangle are, X,2X,and X
2. X+2X+X=180° (angles sum property of a triangle)
3. 4X=180°
4. X=45°
5. so, angles of this triangle 45°,90°and45°
6. Classify this triangle as right angled triangle and isosceles triangle.

Answer 2

$angle \: sum \: of \: triangle \: is180 \\ 1x + 2x + 1x = 180 \\ 4x = 180 \\ x = 180 \div 4 \\ = 45$

$angles \: \: \: 1x = 1 \times 45 = 45 \\ \: \: 2x = 2 \times 45 = 90 \\ 1x = 1 \times 45 = 45$
