Quadrilateral Proofs Worksheets. How to Write Quadrilateral Proofs - When it comes to math, you have to be able to prove that what you're doing is correct. When it comes to geometry, it is the same. In geometry, you'll often be asked to prove that a certain shape is, indeed, that certain shape. For example, you might be shown a quadrilateral ... So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length. 12 comments.Proving a Quadrilateral is a Parallelogram Reasons To prove that a quadrilateral is a parallelogram, show that it has any one of the following properties: Both pairs of opposite sides are congruent. o If both pairs of opposite sides of a quadrilateral are congruent, the quadrilateral is a parallelogram.Prove theorems about quadrilaterals, including properties of parallelograms, rectangles, rhombi, and kites. ...
