Why Study Geometry? - Expii
If you have a shape or object, you might care about its geometry. For example, you might want to know the length of an object, in meters, feet, or some other unit. So we study geometric objects (points, lines, angles, circles, squares, etc.), properties (parallel, perpendicular, etc.), and measurements (length, angle measure, area, volume, etc.), and the relations between them (like the famous Pythagorean theorem).
