Geometry involves objects and the shapes of those objects. Shapes of objects consist of points, lines and circles. Geometry is used daily in the form of construction, navigation, mapping, surveying, architecture, crime scene investigations and even in billiards. Most sports use a geometric sphere called a ball. Courts and playing fields are made of geometric circles, arcs and lines. Where a player stands or moves to involves geometry. A chart showing geometric shapes would help in understanding what geometry involves.
