What is the contrapositive?
"If two lines are perpendicular, then they form four right angles."

• If two lines form four right angles, then they are not perpendicular. 
• If two lines form four right angles, then they are perpendicular. 
• If two lines are not perpendicular then they do not form four right angles. 
• If two lines do not form four right angles, then they are not perpendicular. 

What is the converse?
"If lines are parallel, then same side interior angles are supplementary."

• If the same side interior angles are not supplementary, then the lines are not parallel. 
• If the lines are not parallel, then the same side interior angles are not supplementary.
• If same side interior angles are supplementary, then the lines are parallel. 
• If the lines are parallel, then the same side interior angles are not supplementary.

What is the inverse?
"If the two smallest sides add to be larger than the third side, then it is a triangle."

• If it isn't a triangle, then the third side is larger then the two smallest sides. 
• If the two smallest sides do not add to be larger than the third side, then it is not a triangle. 
• If it is a triangle, then the two smallest sides add to be larger than the third side. 
• It is a triangle if and only if the two smallest sides add to be larger than the third side.
