Question

If the vertex angle of an isosceles triangle is 90 degree then find the base angles

Answer 1

Answer:

the vertex angle of an isosceles triangle is 90°

let, the base angles is x

by the condition

x * x * 90° =180°

x *x = 180° -90°

2x = 90 °

x = 90° /2

x = 45°

Answer 2

Hence,the base angle of the angle of isosceles triangle is 45°.

Step-by-step explanation:

We know that the two angles of the isosceles tringle is equal

Now,

Let the base angle be x,

then

x*x*90°=180°

2x=180°−90°

2x=90°

x=2/90°

∴x=45..

Hence,the base angle of the angle of isosceles triangle is 45°.
