If you have school sprit, then the team feels great. If you wear school colors, then you have school sprit. If you have school sprit, then the team feels great. If you wear the school colors, then the team will feel great. If you wear the school colors, then the team will feel great.

1 - $500 Show the conjecture is false by finding a counterexample: The square roof of number x is always less than x Show the conjecture is false by finding a counterexample: The square roof of number x is always less than x

2 - $100 Fill out the table: Fill out the table: Answer: Answer: Conditional: If X, then Y. Contrapositive: If not Y, then not X. Converse: If Y, then X. Inverse: If not X, then not Y. Conditional:Contrapositive: Converse:Inverse:

2 - $200 Write the if-then form and converse from the following statement: “Black bears live in North America” Write the if-then form and converse from the following statement: “Black bears live in North America” If-then: If a bear is black, then it lives in North America. If-then: If a bear is black, then it lives in North America. Converse: If a bear lives in North America, then it is a black bear. Converse: If a bear lives in North America, then it is a black bear.

2 - $300 Write the inverse form and contrapositive from the following statement: “Black bears live in North America” Write the inverse form and contrapositive from the following statement: “Black bears live in North America” Inverse: If a bear is not black, then it does not live in North America. Inverse: If a bear is not black, then it does not live in North America. Contrapositive: If a bear does not live in North America, then it is not a black bear. Contrapositive: If a bear does not live in North America, then it is not a black bear.

2 - $400 Rewrite the bi-conditional statement as a conditional statement and its convers: Rewrite the bi-conditional statement as a conditional statement and its convers: A point is a midpoint of a segment iff it divides the segment into two congruent segments. A point is a midpoint of a segment iff it divides the segment into two congruent segments. Conditional: If a point is a midpoint of a segment, then it divides the segment into two congruent segments. Conditional: If a point is a midpoint of a segment, then it divides the segment into two congruent segments. Convers: If a point divides a segment into two congruent segments, then the point is the midpoint of segment. Convers: If a point divides a segment into two congruent segments, then the point is the midpoint of segment.

2 - $500 Write the converse of each true statement. If converse is also, true than write the bi- conditional statement. Write the converse of each true statement. If converse is also, true than write the bi- conditional statement. If two circles have the same diameter, then they have the same circumference. If two circles have the same diameter, then they have the same circumference. Convers: If two circles have the same circumference, then they have the same diameter. Convers: If two circles have the same circumference, then they have the same diameter. True True Bi-Conditional: Two circles have the same circumference, iff they have the same diameter.
