Question

true or false. consecutive angles in a parallelogram are congruent.

Answer 1

False. If you think about it, the angles in a parallelogram alternate between acute and obtuse, so they can't be congruent. (Unless it's a square, which is a special case of a parallelogram)

Answer 2

False. Consecutive angles of a parallelogram are supplementary. This is because they are same-side interior angles formed when two parallel lines are cut by a transversal.
