Proving Quadrilaterals Given the four coordinates, draw a diagram of your quadrilateral. Then use distance formula and slope to determine which definition best fits your quadrilateral. After you have completed your calculations, write up your argument in a formal paragraph proof. R(1, 2), S(3, 3), T(5, 2), V(3, 1) Math Work: Proof/Argument:
Basic Quadrilateral Proofs For each of the following, draw a diagram with labels, create the givens and proof statement to go with your diagram, then write a two-column proof. Make sure your work is neat and organized. Quadrilateral Proof: 1. Prove that the sum of the interior angles of a quadrilateral is 360𝑜. Given: Quadrilateral
Theorems Dealing with Parallelograms
THEOREM: If a quadrilateral is a parallelogram, it has diagonals which form 2 congruent triangles. Use the following, to PROVE a parallelogram: DEFINITION: A parallelogram is a quadrilateral with both pairs of opposite sides parallel.
2011年1月5日 · • The quadrilateral is equilateral. • The quadrilateral is a parallelogram and a diagonal bisects opposite angles. To prove a square, prove ONE of the following: • The quadrilateral is a rectangle with two consecutive sides congruent. • The quadrilateral is a rhombus with one right angle.
Parallelogram Proofs - Learn How to Prove a Parallelogram …
2023年8月3日 · There are 5 basic ways to prove a quadrilateral is a parallelogram. They are as follows: Let us now prove the above statements one by one. Prove that opposite sides of a parallelogram are congruent. To prove: AB ≅ CD, AD ≅ BC. Proof: Given: AB ∥ CD, AD ∥ BC. Draw in a diagonal AC. Prove that opposite sides of a parallelogram are parallel.
Theorems about Quadrilaterals
2024年11月1日 · To prove that a rhombus is a parallelogram, you must prove that it either satisfies the definition of a parallelogram or satisfies any of the theorems that prove that quadrilaterals are parallelograms. Here is a paragraph proof: A rhombus is a quadrilateral with four congruent sides, therefore opposite sides of a rhombus are congruent.
