Question

in triangle pqr if PQ = QR = PR then prove that angle P = angle Q = angle R = 60 degree

Answer 1

Draw a perpendicular. Now prove the two traingles formed congruent. Now draw another perpendicular and do the same. This way all angles will come equal

Answer 2

Answer:

Step-by-step explanation:

As PQ=PR, and angle R= 60, angle Q will also be 60.

REASON: Angles opposite to equal sides are equal.

That's all; hope it's clear ☺️☺️
