Simple geometry is a branch of mathematics that deals with the study of basic shapes and their properties, such as points, lines, angles, and planes.
The main types of simple geometry are Euclidean geometry, which deals with flat surfaces and shapes, and non-Euclidean geometry, which deals with curved surfaces and shapes.
Some common examples of simple geometry in everyday life include measuring angles with a protractor, drawing shapes using rulers and compasses, and calculating area and perimeter of objects.
The formula for calculating the area of a shape depends on the type of shape. For example, the area of a rectangle is calculated by multiplying its length by its width, while the area of a circle is calculated by multiplying the square of its radius by pi.
Simple geometry is used in various fields such as architecture, engineering, art, and design. It is also used in navigation, map-making, and computer graphics.
