Question

The three angles of a triangle are in the ratio
1:2 : 1. Find all the angles of the triangle.
Classify the triangle in two ways.​

Answer 1

Step-by-step explanation:

let the constant be x

according to give. condition angles are in ratio of 1:2:1

1x+2x+1x=180 angle sum property

4x=180

X=45

Answer 2

Answer:

45, 45 and 90 degrees

Step-by-step explanation:

As a triangles angles sum up to 180 degree

we will take each angle as x

as the ratio of the angles are 1,1 and 2.

1x + 2x +1x = 180

4x = 180

x = 180/4

x = 45

Therefore,

1x=45

1x=45

2x = 45*2=90

As the two angles are equal it is an isosceles triangle..
