Question

I need help with the blanks. This geometry proofs.

Answer 1

Explanation:

First problem:

blank 2) on the left: PR = PQ + QR

blank 3) on the right: Replace PR in statement 1) with what we just completed in statement 2. Therefore:

2PQ = PR

2PQ = PQ + QR

blank 4) on the right: Subtract PQ from both sides, therefore

2PQ = PQ + QR

2PQ - PQ = PQ + QR - PQ

PQ = QR
