Question

If the two triangles below are congruent, what is the measure of ∠P?

26°
43°
63°
111°

Answer 1

180

Explanation:

∠C corresponds to ∠R , so m∠R = 111° .

26° + 111° + 43° = 180°

Answer 2

If the triangles are congruent then the corresponding angles would be the same,

Angle A = Q

C = R

A = P

So now we know Q = 26 and R would = 111

The 3 inside angles of a triangle need to equal 180

So P = 180 - 26 - 111 = 43 degrees.
