Section 5.7 – Proofs Using Coordinate Geometry

These are not 2-column proofs. They are verification proofs. You will need to know the following formulas:

a.) distance formula

b.) midpoint formula

c.) slope

USE:

Distance	Midpoint	Slope
Congruent sides	Bisect	//,
Congruent lengths	midpoint	Right

You will also need to know all of the properties of the various polygons.

Such as:

1. triangles (right, isosceles, equilateral)
2. squares
3. rectangles
4. parallelograms
5. trapezoid
