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
