Properties and Types of Triangles is the fifth of eight self-paced lessons in the “Lines, Angles, and Triangles” section of KET’s GED® Geometry Professional Development Online Course. This lesson demonstrates the types of triangles students may encounter on the GED® Mathematics Test. It shows how they need to combine basic knowledge of triangles with the ability to solve for an angle when it is unknown.
