Criteria proving a quadrilateral is parallelogram. 1) If a quadrilateral has one pair of sides that are both parallel and congruent. 2) If all opposite sides of the quadrilateral are congruent. 3) Both pairs of opposite sides are parallel. 4) Opposite angles are congruent. 5) Diagonals bisect.
we make based on whether we are given that a certain quadrilateral is a parallelogram, or if we want to prove that the quadrilateral is a parallelogram. Let’s take a look at these statements so that we understand how to use them properly in our proofs. Given a Parallelogram
Show that a quadrilateral is a parallelogram in the coordinate plane. Given a parallelogram, you can use the Parallelogram Opposite Sides Theorem (Theorem 7.3) and the Parallelogram Opposite Angles Theorem (Theorem 7.4) to prove statements about the sides and angles of the parallelogram.
Area = base x height. Here are the steps to finding the area of a parallelogram: Identify the base and height of the parallelogram. Multiply the base and height together. The product is the area of the parallelogram. For example, let’s say we have a parallelogram with a base of 5 cm and a height of 8 cm. The area of the parallelogram would be:
