  1. TRUE or FALSE? If FALSE, correct the mistake. • If two angles are complementary, then the sum of their measures is 180 degrees.

  2. TRUE or FALSE? If FALSE, correct the mistake. • A rhombus is a parallelogram that has four congruent sides.

  3. TRUE or FALSE? If FALSE, correct the mistake. • If an “if-then” statement is true, then its converse is always true.

  4. TRUE or FALSE? If FALSE, correct the mistake. • If a transversal crosses two parallel lines, then the alternate interior angles formed are supplementary.

  5. TRUE or FALSE? If FALSE, correct the mistake. • A median in a triangle is a segment connecting a vertex to the midpoint of the opposite side.
