Alisha makes four statements about angle relationships. Mark which statement is True.

1. 1. Supplementary angles are equal

2. 2. Alternate interior angles are supplementary

3. 3. Same-side interior angles are complimentary

4. 4. Corresponding angles are congruent

• 1. Supplementary angles are equal

• 1. Alternate interior angles are supplementary

• 1. Same-side interior angles are complimentary

• 1. Corresponding angles are congruent

Organize this statement to reflect the correct order.

(c) Contrapositive

,

(d) Biconditional

• If a shape has four equal sides, then it is a square.

• A shape is a square if and only if it has four equal sides.

• If a shape is not a square, then it does not have four equal sides.

• If a shape is not a square, then it does not have four equal sides.

Match the following statements to the prompt.

• If a quadrilateral does not have four right angles, then it is not a square

• Inverse

• If a quadrilateral is not a squarethen itdoes not have four right angles

• Biconditional

• If a quadrilateral has four right angles, then it is a square

• Converse

• A quadrilateral is a square if and only if it has four right angles
