GED® Geometry: Pythagorean Theorem & Coordinate Geometry

A deep GED® Geometry course that connects right triangles to the coordinate plane. Students master the Pythagorean Theorem -- finding the hypotenuse, finding a missing leg, and using Pythagorean triples -- then apply the same idea on the grid through the distance formula, midpoint formula, and slope. Every lesson has a labeled diagram and an interactive self-check, and every practice question comes with a full teaching explanation and a Pro tip, so wrong answers turn into learning.
