Given the following conditional statement:

If m∠F = 100° and ∠F and ∠G are supplementary, then m∠G = 80°.

Part A: How is proof by contradiction different from a traditional proof? What assumption statement will begin proof by contraction for the given conditional statement? (3 points)

Part B: Prove the given conditional statement is true by contradiction. (3 points)

if you dont mind please write a response i can insert.
