9: Prove theorems about lines and angles. Theorems include: vertical angles are congruent; when a transversal crosses parallel lines alternate interior angles
because opposite angles in a parallelogram are congruent. are right angles since all right angles are congruent. ANSWER: Given: is a right angle. Prove:.
parallelograms
Adjacent angles of a parallelogram are supplementary. Using opposite angles test for parallelogram prove that every rectangle is a parallelogram.
