Khan Academy: Quadrilateral Problems on the Coordinate Plane

A quadrilateral is drawn on the coordinate plane, and eighth grade geometers find the length of each side and the diagonals by applying the Pythagorean theorem. 

Introduce your class to the basics of coordinate planes. The reading passage included here describes ordered pairs and the different quadrants on a coordinate grid. Learners read the passage and respond to five related questions.

Class members investigate rectangles on the coordinate plane. They determine the length of line segments in the coordinate plane with the same x-coordinate or same y-coordinate and then solve geometric problems involving perimeter and...

Keep young mathematicians on point with this coordinate plane worksheet. From plotting ordered pairs to identifying the quadrant and coordinates of specific points, this resource covers all the basic skills students need to have when...

Sal's goal in this video is to "familiarize ourselves with the x, y-coordinate plane." If your pupils have blank expressions when you present them with graphing problems, this video will be a great help to clear up the basics.

You can't get from point A to point B if you can't find point A. Using a helpful video lesson, viewers learn how to plot points on a coordinate plane. The instructor emphasizes the vertical and horizontal distance of the x and...

A set of four practice problems finding the points of quadrilaterals on a coordinate plane.

In this exercise, students practice finding reflecting points on the coordinate plane. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

Everything you need to understand the rectangular coordinate system is explained in this easy to follow video. Great for elementary to middle schoolers learning about plotting points, graphing, and locating points on a coordinate grid....

Demonstrates how to plot ordered pairs of points across all four quadrants of a coordinate plane. Includes practice problems and explanations of their solutions.
