Answer 2

Step-by-step explanation:

let the angle =x

let the other two angles =y each

we know that sum of othe two angles is equal to x.that is 2y=x

x+y+y=180°(angle sum property)

x+2y=180°

x+x=180°

2x=180°

x=180°÷2

x=90°

if one angle of a triangle is right angle then it is called right angled triangle
