Let's prove the following theorem:
if WX || YZ and m∠ZXR = 180, then m∠YZR = m∠WXR
Proof:
Given
1 | WX || YZ |
---|---|
2 | m∠ZXR = 180 |
# | Claim | Reason |
---|---|---|
1 | m∠YZX = m∠WXR | if WX || YZ and m∠ZXR = 180, then m∠YZX = m∠WXR |
2 | m∠YZX = m∠YZR | if m∠ZXR = 180, then m∠YZX = m∠YZR |
3 | m∠YZR = m∠WXR | if m∠YZX = m∠YZR and m∠YZX = m∠WXR, then m∠YZR = m∠WXR |
