How do you prove a quadrilateral is a rectangle with coordinates?

There are a few ways to prove a quadrilateral is a rectangle. Here are three of the easiest ways: 1) Show all angles are 90°; 2) Show that one pair of sides is parallel and that two opposite angles are 90°; 3) Show the diagonals bisect each other and are of equal length.

How do you check if given four points form a rectangle?

1. translate the quadrilateral so that one of its vertices now lies at the origin.
2. the three remaining points form three vectors from the origin.
3. one of them must represent the diagonal.
4. the other two must represent the sides.
5. by the parallelogram rule if the sides form the diagonal, we have a parallelogram.

How to Prove that a Quadrilateral Is a Square

1. If a quadrilateral has four congruent sides and four right angles, then it’s a square (reverse of the square definition).
2. If two consecutive sides of a rectangle are congruent, then it’s a square (neither the reverse of the definition nor the converse of a property).
