A parallelogram is a flat shape with four straight, connected sides so that opposite sides are congruent and parallel. Write a proof to show that opposite sides of a parallelogram are congruent. 5) The diagonals of a parallelogram … Which statement can be used to prove that a given parallelogram is a rectangle? Prove that both pairs of opposite sides are congruent. 2) If each pair of opposite sides of a quadrilateral is equal then it is a parallelogram. Strategy: how to prove that opposite sides of a parallelogram are equal. The diagonals of a parallelogram bisect each other. 1) In a parallelogram, opposite sides are equal. The opposite sides are equal and parallel; the opposite angles are also equal. A) The opposite sides of the parallelogram are congruent. View Untitled document (3).pdf from MATH 100 at Basha High School. Prove that one pair of opposite sides is both congruent and parallel. Step-by … B) The diagonals of the parallelogram are congruent. b. Once again, since we are trying to show line segments are equal, we will use congruent triangles.Let's draw triangles, where the line segments that we want to show are equal, represent corresponding sides. parallelogram, because opposite sides are congruent and adjacent sides are not perpendicular Which statement explains how you could use coordinate geometry to prove the diagonals of … 4) If in a quadrilateral, each pair of opposite angles is equal then it is a parallelogram. Opposite angels are congruent (D = B). Prove that the opposite sides of a parallelogram are congruent. (Recall that a parallelogram is a four-sided figure in which both pairs of opposite sides are p… If one angle is right, then all angles are right. Each diagonal of a parallelogram separates it into two congruent … Try to move the vertices A, B, and D and observe how the figure changes. This Lesson (Proof of Opposite sides of a parallelogram are equal) was created by by chillaks(0) : View Source, Show About chillaks : am a freelancer In this lesson we will prove the basic property of a parallelogram that the opposite sides in a parallelogram are equal. c. No; you cannot prove that the quadrilateral is a parallelogram. Be sure to create and name the appropriate geometric figures. a. Yes; opposite angles are congruent. Prove that the diagonals bisect each other. (10 Math III Unit 7-4 Theorems about Parallelograms Notes Name: _____ 1. To prove a quadrilateral is a parallelogram, you must use one of these five ways.
