How to fill out coordinate proof and quadrilaterals

How to fill out coordinate proof and quadrilaterals:

1. Start by understanding what a coordinate proof is. A coordinate proof is a method used to prove geometric theorems using algebra and the coordinate plane.
2. Identify the given information. Look for any coordinates or measurements that are provided in the problem. Write down all the given information.
3. Plot the points on the coordinate plane. Use the given coordinates to plot the points of the quadrilateral on a coordinate plane. Label each point accordingly.
4. Determine the slopes of the sides. Find the slopes of each side of the quadrilateral by using the coordinates of the points. Remember that the slope of a line can be calculated using the formula: (change in y) / (change in x).
5. Calculate the distances of the sides. Use the distance formula to find the lengths of each side of the quadrilateral. The distance formula is: √((x2-x1)^2 + (y2-y1)^2).
6. Analyze the properties of the quadrilateral. Look for any special properties or characteristics of the quadrilateral. For example, if it is a parallelogram, opposite sides would be parallel. If it is a rectangle, all angles would be right angles.
7. Make connections and form proofs. Use the properties and measurements you have calculated to prove the given theorem or statement. Connect the dots between the coordinates, slopes, distances, and properties to construct a logical proof.
