Plane Coordinate Geometry

In this coordinate geometry worksheet, students determine the coordinates of an unknown vertex. They write a coordinate proof supporting their findings. This four-page worksheet contains examples, explanations, and 8 problems. Answers...

This unit on connecting algebra and geometry covers a number of topics including worksheets on the distance formula, finding the perimeter and area of polynomials, the slope formula, parallel and perpendicular lines, parallelograms,...

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. 

Who knew quilting would be so mathematical? Introduce linear equations and graphing while working with the lines of pre-designed quilts. Use the parts of the design to calculate the slope of the linear segments. The project comes with...

To work through the complexity of coordinate geometry pupils make the connection between the coordinate plane and the complex plane as they plot complex numbers in the 11th part of a series of 32. Making the connection between the two...

Use transformations to coordinate the coordinates! After graphing a transformation, class members examine the patterns in the coordinates. They repeat the process for each type of transformation and end by generalizing their conclusions....

You'll be ready to plot something after a lesson on coordinate geometry! The video instructor begins by discussing how to plot four points to create a quadrilateral. The second example demonstrates finding the area and perimeter from the...

Students solve proofs dealing with the coordinate plane. In this geometry lesson, students verify properties of triangles and quadrilaterals.

Students identify the point of intersection of two lines. In this geometry lesson, students identify the pair of coordinates on a coordinate plane where two lines cross. They identify the lines as parallel or perpendicular.

Where is the point? Given three points on the coordinate plane, the video walks through the steps to find the location of the fourth point to create a given special quadrilateral. The narrator first determines the coordinates of the...
