When taking the converse of a statement we_____ the hypothesis and the conclusion.

• negate
• highlight
• switch
• switch and negate

If it is a triangle, then it has three sides. What is the conclusion?

• It is a triangle
• It has three sides
• It is a polygon
• It sums to 180

When taking the inverse of a statement, we_______ the hypothesis and the conclusion.

• negate
• switch

Given: If I have a Siberian Husky, then I have a dog
Identify the contrapositive

• If I do not have a Siberian Husky, then I do not have a dog
• If I do not have a dog, then I do not have a Siberian Husky.
• If I have a dog, then I have a Siberian Husky
• If I have a dog, then I don't have a Siberian Husky

If two angles are supplementary, then they have a sum of 180. Is the inverse true?

• Yes, if two angles are not supplementary, then they do not add to 180
• no, if angles don't add to 180, they can still be supplementary
• no, Supplementary angles add to 90
• yes, supplementary angles add to less than 180

When taking the converse we ___________ the hypothesis and conclusion.

• negate
• switch
• leave the same
• switch and negate

What does this mean?

• Conditional 
• Inverse 
• Converse 
• Contrapositive 

Given, "If angles are congruent, then the measures of the angles are equal." Identify the contrapositive.

• If the measures of the angles are equal, then the angles are congruent.
• If angles are not congruent, then the measures of the angles are not equal.
• If the measures of the angles are not equal, then the angles are not congruent.
• If the angles are not congruent, then the measure of the angles are equal.

Given, "If angles are congruent, then the measures of the angles are equal." Identify the converse.

• If the measures of the angles are equal, then the angles are congruent.
• "If angles are not congruent, then the measures of the angles are not equal."
• If the measures of the angles are not equal, then the angles are not congruent.
• If the angles are not congruent, then the measure of the angles are equal.
