Criss-crossing
In this resource students are given four coordinate points and asked to find the equation of the lines that connect them. The four lines intersect to form a rectangle- can students find the area of the rectangle?
Each student worksheet contains different coordinate points, but the solutions all have something in common.
The mathematics required to solve the problem includes; equations of lines, finding the equation of a perpendicular line, determining midpoints, and solving simultaneous equations.
There is also an interactive Geogebra file to accompany the problem.
