Geometry is a branch of mathematics that deals with the measurement properties and relationships of points lines angles surfaces and solidsThere are two types of geometry 2D geometry or plane geometry and 3D geometry or solid geometryFlat shapes like squares circles and triangles are a part of flat geometry and are called 2D shapes. A formula is a mathematical equation to solve a geometry problem while a theorem is a statement that is proved using previously known facts. An example of geometry can be the calculation of a triangles angles.
