Proof by contradiction is a method that assumes the opposite of what is stated. If a contradiction can be shown, it will indirectly lead to the statement being true.
So for this example, the contradiction would: Assume that <G does NOT equal 80 degrees.

ty but how is proof by contradiction different from a traditional proof?

Traditional proofs: They involve the use of direct, logical statements, theorems, and deductions.
Contradiction: It is an indirect proof that assumes the OPPOSITE of what is being statement. The goal of contradiction is to arrive at a false assumption.

thank you now i just have to prove the statement is true by contradiction
Luigi0210:
And to PROVE it by contradiction you have to break it up into two cases:
Case 1: Assume that <G is greater than 80 degrees. Assume it is like 90 degrees, that would mean that 100+90 = 190 degrees, making it NOT supplementary.
Case 2: Assume that <G is less than 80 degrees. Same as above, it would give a value LESS than 180 degrees, thus also NOT complementary.
In both cases, a contradiction, so <G has be 80 degrees.
