## GEOMETRY FORMULAS

Geometry formulae are used to determine the dimensions, perimeter, area, surface area, volume, and other properties of geometrical shapes. Geometry is a branch of mathematics concerned with the connections between points, lines, angles, surfaces, solids, measurements, and qualities.

Plane geometry is concerned with flat shapes that may be drawn on a sheet of paper. Two-dimensional lines, circles, and triangles are examples. Plane geometry is also called two-dimensional geometry.

All of the two-dimensional figures have only two dimensions: length and width. It does not consider the depth of the shapes. Plane figures include the square, triangle, rectangle, circle, and so on.

Solid geometry is concerned with three-dimensional objects such as cubes, prisms, cylinders, and spheres. It is concerned with the figure’s three dimensions: length, width, and height. However, certain solids do not have faces (e.g., spheres).

Solid geometry is the study of three dimensions in Euclidean space. The objects around us are three-dimensional. The rotation of two-dimensional forms yields all three-dimensional shapes.

The following is a sample of several geometry formulae for you to use based on the specific shape.
