Geometry is frequently challenging for students because every problem involves a figure that students must use to solve the problem. Each new concept is introduced in an easy to understand way, using example problems that are worked out step-by-step and line-by-line to completion. This program teaches students how to work with and identify quadrilaterals, which are just 4-sided geometric objects. Rectangles, squares, parallelograms, rhombuses and more are covered. Various theorems are presented that involve angles inside of quadrilaterals.
