Recall: A rectangle is a quadrilateral in which both pairs of opposite sides are parallel and congruent, andLine n is a transversal. And now we have two corresponding angles are congruent. We assumed that from the get-go that we could find two quadrilateral, where these two corresponding angles are congruent. But if you have two corresponding angles congruent like this, that means that these two lines must be parallel.When it comes to proving the properties of quadrilaterals, you need to rely on established theorems and relationships between sides, angles, and diagonals. Here are a few methods commonly used to prove the properties of quadrilaterals. 1. SSSS Criterion: This criterion is a direct consequence of the Side-Side-Side (SSS) congruence theorem.
