What Is the definition of Geometry?

Solution:

Geometry is defined as the branch of mathematics concerned with the properties and relations of points, lines, surfaces, solids, and higher dimensional shapes and figures. The word geometry is derived from the combination of the Greek words geo (“Earth”) and metron (“measure”) for the measurement of the Earth.

Geometry studies the sizes, shapes, positions angles and dimensions of things. Flat shapes like squares, circles, and triangles are a part of flat geometry and are called 2D shapes. These shapes have only 2 dimensions, the length and the width.

Geometry also studies 3D shapes like spheres, cylinders, cones, prisms, pyramids and so on.
