Two angles whose sum equals 180° are called...

• supplementary angles.

• obtuse angles.

• complementary angles

• a straight line.

What is the measure of an angle that is complementary to a 45° angle?

• 45°

• 90°

• 135°

• 180°

What is the contrapositive of the statement: "If a polygon is a quadrilateral, then it is a trapezoid"?

• If a polygon is not a trapezoid, then it is not a quadrilateral.

• If a polygon is a trapezoid, then it is a quadrilateral.

• If a polygon is not a quadrilateral, then it is not a trapezoid.

• A rectangle is also a quadrilateral.

Rewrite the following statement as a biconditional:

• If two angles add up to 180^o then they are supplementary.

• Angles are supplementary if they add to 180^o.

• Two angles are supplementary if and only if the sum of the measure of the two angles is 180^o.

• If two angles sum does not equal 180^o then they are not supplementary.

What is the definition of complementary angles?

• Angles that add up to 90°

• Angles that add up to 180°

• Angles that are equal

• Angles that are adjacent

Which of the following provide a counterexample to the claim:

"If two angles are supplementary, then they are not congruent."
