Answer 1

Answer:

let angles of triangle be 1x,2x,1x

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

x=45 degree

Step-by-step explanation:

angles are 45,90,45 which forms a right angled triangle and isosceles triangle

Answer 2

Given :-

The three angles of a triangle are in the ratio of 1:2:1.

To Find :-

Angles

Solution :-

Let the ratio be x,2x and x

⇒ x + 2x + x = 180

⇒ 4x = 180

⇒ x = 180/4

⇒ x = 45

Angles are

x = 45°

2x = 2(45) = 90°

x = 45°

Triangle can be classified as

Right  angled triangle

Isosceles triangle
