and C=45o

then it is _____ triangle A. Equilateral B. Isosceles C. Scalene D. Acute​

Answer 1

Answer:

B) It's Isosceles Triangle..

Because

angleA = 90°

angleC = 45°

angleB = 180-(90+45)

= 45°

When two angles are equal, then angles opp to their sides are equal...

Hence it is an isosceles triangle
