Proof: Tangent
Let's prove the following theorem:
if tangent of (m∠BCA) = (distance AB) / (distance BC), then tangent of (m∠BCA) = (distance BA) / (distance CB)
Proof:
Proof Table
# | Claim | Reason |
---|---|---|
1 | (distance AB) / (distance BC) = (distance BA) / (distance CB) | (distance AB) / (distance BC) = (distance BA) / (distance CB) |
2 | tangent of (m∠BCA) = (distance BA) / (distance CB) | if tangent of (m∠BCA) = (distance AB) / (distance BC) and (distance AB) / (distance BC) = (distance BA) / (distance CB), then tangent of (m∠BCA) = (distance BA) / (distance CB) |
