Proof: Angle Symmetry 2
Let's prove the following theorem:
if m∠ABC = m∠XYZ, then m∠CBA = m∠ZYX
Proof:
Proof Table
# | Claim | Reason |
---|---|---|
1 | m∠ABC = m∠ZYX | if m∠ABC = m∠XYZ, then m∠ABC = m∠ZYX |
2 | m∠ABC = m∠CBA | m∠ABC = m∠CBA |
3 | m∠CBA = m∠ZYX | if m∠ABC = m∠CBA and m∠ABC = m∠ZYX, then m∠CBA = m∠ZYX |
