Question

in triangle PQR prove that angle p+angle Q+angle R=180°​

Answer 1

Answer:

in triangle PQR prove that angle p+angle Q+angle R=180°

Answer 2

Step-by-step explanation:

Complementary angles means when angles add up to 90 degree.

Since sum of a triangle is 180 degree, so if two angles angle P and angle Q are complementary then angle R will be 90 degree

∠P+∠Q+∠R= 180

0

90+∠R= 180

0

∠R= 90

0
