Question

abc is a right angled triangle in which angle a=90degree and ab=ac find angle b and angle c

Answer 1

We know that, angles opposite to equal sides of a triangle are equal.

=> <ABC = <ACB

Let <ABC = a

By angle sum property of triangle,

a + a + 90 = 180

=> 2a = 90

=> a = 45

<ABC = 45°

<ACB = 45°
