Quadrilateral proofs

Correct answer: False. Explanation: Just because a triangle has two sides and one angle congruent to the two sides and angle of another triangle does not guarantee these two triangles’ congruence. For the two triangles to be congruent, the two sides that are congruent must contain the congruent angle as well.
