## ILikebubbles 3 years ago Read the statement shown below. “If two supplementary angles are congruent, then they are right angles.” Which of these is the contrapositive of the statement? If two supplementary angles are not right angles, then they are not congruent. If two supplementary angles are not congruent, then they are not right angles. If two supplementary angles are right angles, then they are congruent. If two supplementary angles are congruent, then they must be right angles.

Well a contrapositive would be negating both terms and reversing the direction of an inference. Now which one of those sounds like that?

statement : if a, then b contrapositive : if NOT b, then NOT a

3. lolly

i think its D?

4. Geometry_Hater

Hmmm are you sure about that lolly?

5. Geometry_Hater

listen well to what gameshie said then look at the original statement.

6. ILikebubbles

What is it then because in confused?

7. Geometry_Hater

“If two supplementary angles are congruent, then they are right angles.” Reverse it

8. ILikebubbles

So they are not congruent?

9. Geometry_Hater

if they are not right angles

Thanks!

no problem. ;)
