How do you do proofs in coordinate geometry?
When developing a coordinate geometry proof:
- Plot the points, draw the figure and label.
- State the formulas you will be using.
- Show ALL work.
- Have a concluding sentence stating what you have proven and why it is true. Usually a theorem or a definition is needed here.
What formula can be used in writing a coordinate proof?
You can use the distance formula or the Pythagorean Theorem to do this. Because all four sides are the same length, all four sides are congruent. SECOND: Find the slopes of all four sides and verify that adjacent sides have opposite reciprocal slopes and therefore are perpendicular, creating right angles.
What does a coordinate proof look like?
The coordinate proof is a proof of a geometric theorem which uses “generalized” points on the Cartesian Plane to make an argument. The method usually involves assigning variables to the coordinates of one or more points, and then using these variables in the midpoint or distance formulas .

What is a geometric proof?
Geometric proofs are given statements that prove a mathematical concept is true. In order for a proof to be proven true, it has to include multiple steps. These steps are made up of reasons and statements.
When writing a coordinate proof why are variables used instead of numbers as coordinates for the vertices of a figure?
When you use variables to represent the coordinates of a figure in a coordinate proof, the results are true for all figures of that type. Place each figure in a coordinate plane in a way that is convenient for finding side lengths.
What makes a coordinate proof different from the other types of proofs you have written so far?
How is a coordinate proof different from other types of proofs you have studied? You do not need to write a plan for a coordinate proof. You do not have a Given or Prove statement. You have to assign coordinates to vertices and write expressions for the side lengths and slopes of segments.
