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. A(1, -4), B(1, 1), C(-2, 2), D(-2, -3) Math Work: Proof/Argument:

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.You can prove that triangles are congruent by SSS, SAS, ASA, AAS, or HL. Learn how to use each of those criteria in proofs in this free geometry lesson!12.1 Proofs and conjectures (EMA7H) We will now apply what we have learnt about geometry and the properties of polygons (in particular triangles and quadrilaterals) to prove some of these properties. We will also look at how we can prove a particular quadrilateral is one of the special quadrilaterals. This video shows how to prove that the the ...Draw in diagonals. One of the methods for proving that a quadrilateral is a kite involves diagonals, so if the diagram lacks either of the kite’s two diagonals, try drawing in one or both of them.

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.This geometry video tutorial provides a basic introduction into proving kites using two column proofs.

General Information Regarding Quadrilaterals (w/ symmetry info: rotational & reflectional) •. The Quadrilateral Family (and Properties) •. Observing Properties through Symmetry. •. Theorems Dealing with Parallelograms (with proofs of theorems) •. Theorems Dealing with Rectangles, Rhombuses and Squares (with proofs of theorems)Here is a paragraph proof: A rhombus is a quadrilateral with four congruent sides, therefore opposite sides of a rhombus are congruent. Parallelogram theorem #2 converse states that “if the opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram”. Therefore, a rhombus is a parallelogram.This geometry video tutorial provides a basic introduction into the different types of special quadrilaterals and the properties of quadrilaterals.

Explanation: Just because a triangle has two sides and one angle congruent to the two sides and angle of another triangle does not guarantee these two triangles’ congruence. For the two triangles to be congruent, the two sides that are congruent must contain the congruent angle as well.Learn how to identify and verify parallelograms using theorems and characteristics.
