Question

if two angles of a triangle are complementary than what type of triangle will formed

Answer 1

It is right angle because if the sum of two angles=complementary=90°, then third angle will be=180-90=90°
Hope this answer helps you!!!

Answer 2

let the2 angles be A & B
third angle be C
Angle A + Angle B = 90° ( given)
A+B+C= 180°. (by ASP)
90°+ C= 180°
C= 180°- 90°
C= 90°
one Angle is 90°
Hence right∆ will be formed.
