# Write a coordinate proof of this statement the diagonals of a square are perpendicular

Example of two-column proof vs. And, I will also show you MY exact thought process when I was thinking about this. Back to Top Let us study about the parallelograms. Parallelograms contain some of the types in it. The diagonals of the parallelograms also bisect each other at the centre point.

The parallelograms and types are discussed in detail with their basic problem solving methods as below. Steps to follow when working on Coordinate Geometry Proofs parallelogram here Step1: First we draw and label the graph. Write down the geometric conditions that are required.

State the formulas that are used Step4: Show all work Step 5: Have a concluding statement stating what you have proven and why it is true.

By finding the slopes and distance of the given quadrilateral we can prove that this given quadrilateral is a parallelogram. Segments BC and DA are parallel since they have equal slopes and also their lengths are seemed to be equal. Therefore the properties of a parallelogram are proved in the given quadrilateral. A trapezoid is a quadrilateral that has one pair of parallel sides and other pair as nonparallel sides. If the 2 non parallel sides are equal then we say the trapezoid is isosceles. Since only 1 pair of sides have equal slope then we get only 1 pair of parallel sides. Hence ABCD is a trapezoid. Now We use distance formula to prove that it is isosceles.PROOF WRITTEN IN 'PARAGRAPH' FORM: Please look at the picture. Since the diagonals are bisecting each other, the line segments marked with one little line are equal, and similarly the line segments marked with double little lines.

We are going to accept the statement of equivalence rather than construct a proof of it.

Theorem (Converse of Theorem ) If two parallel lines are cut by a transversal, then a pair of corresponding angles is congruent. The proof of Theorem provided in the . Question I kind of got confused with this question; Given: line OA is perpendicular to line OC and line OB is perpendicular to line OD.

Prove: angle AOB is congruent to angle DOC. I did this 1. Given caninariojana.com OA is perpendicular to line OC and line OB is perpendicular to line OD 2. if perpendicular.

Write the Given and Prove statements for a proof of the following theorem: If a quadrilateral is a square, then its diagonals are perpendicular.
