1. Complete the paragraph proof
Given: ∠A and ∠B are complementary, and ∠B and ∠C are complementary
Prove: ∠A ≌ ∠C
By definition of complementary angles, m∠A + _____ = 90° and m∠B + m∠C+ _______.
Then, m∠A + m∠B = m∠B + m∠C by the _____________________________. Subtract
m∠B from each side. You get ________= m∠C or _________ ≅ ∠C
