Quadrilateral proofs.

A square’s two diagonals divide each other into two equal segments. A square’s two diagonals divide each of the square’s four right (90-degree) angles into two equal 45-degree angles. Opposite sides of a square are parallel. A square has the most lines of symmetry (four), of all quadrilaterals.Learn how to use the reflexive, symmetric, and transitive properties of equality and congruence in geometric proofs.

Learn more. dunham's mcknight road If one pair of opposite sides of a quadrilateral is parallel, then the quadrilateral is a parallelogram. So once again, a lot of terminology. And I do remember these from my geometry days. Quadrilateral means four sides. A four sided figure. And a parallelogram means that all the opposite sides are 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.
