Shapes: Math Videos

This series explores geometric shapes and their properties. You will learn about quadrilaterals like rhombuses, kites, and parallelograms, and prove key facts about their sides and diagonals. You will also study similar shapes and circles, including arcs and central angles. Geometry builds careful reasoning skills. You should be comfortable with basic angles and triangles.
