Arigjt triangle with two congruent legs is always 45-45-90

right angel triangle means one of the three angel is 90

also it is given that two sides are equal

there for it is an isoselas triangle means other two triangles are equal

let the other two angels be x then

then 90 + x + x = 180

2x = 180 - 90

x = 90 ÷2

× = 45

prof. 90 + 45 + 45 = 180
