Question

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

Answer 1

Answer:

Let the angles be x  2x   x

Step-by-step explanation:

so as we know angle sum property of a triangle

x+2x+x = 180

4x=180

x=180/4=45

so the angles are 45 90 45

Answer 2

Answer:

Let the angles of the triangle ABC where A= Z,B=2Z and C=Z.

Sum of all angles of a triangle = 180°

Z + 2Z + Z. = 180°

4 Z. = 180°

Z. = 180°/4

Z. = 45°

The angles are-

Z = 45°

2Z= 2 * 45° = 90°

Z. = 45°
