Geometry is the branch of mathematics that is concerned with the study of shapes. It concerns their measurements and properties as well as the relationships of points, lines, angles, surfaces, and solids. An angle is a figure that is formed by two rays that have a common endpoint. The sides refer to the rays and the vertex refers to the endpoint. With Alison's geometry courses, you will learn how to easily measure the area of angles.
