Geometry allows us to discover patterns, find areas, volumes; lengths and angles, and improve our understanding of the world we live in. Geometry is all about shapes and their properties. Geometry is one of the first models of math. The word geometry in the Greek dialect interprets the words for "Earth" and "Measure". The Egyptians were one of the first to utilize geometry. The Egyptians utilized right triangles to quantify and appraise land. In our times, geometry is utilized in the fields, designing, structural engineering, medication, drafting, space science, and geology.

Geometry can be divided into:

**Plane Geometry** A flat surface
that extends into infinity in all
directions is known as a Plane.

**Solid Geometry** The branch of math that comprises three-dimensional figures and surfaces.

A Point is an exact location in space. A point has no size.

A **Line** extends indefinitely in a single dimension.

A **Plane** exists in two dimensions.

A **Solid** is a 3-dimensional figure that has width, depth and height.

**Plane Geometry** is about shapes on a flat surface (like on an
piece of paper). The plane has two dimensions: length and width. Keep
in mind, that the plane is infinite in size; the length and width can't be
measured.

**Polygons**

A Polygon is a 2-dimensional shape made of straight lines. Triangles and
Rectangles are polygons.

**The Circle**

A Circle is a perfectly round shape: a line that is curved so that its ends
meet and every point on the line is the same distance from the center.

**Symbols**

Symbols help save time and space for mathematicians. Below is a short
list of common symbols used in Geometry:

** Angles **

The space inside of two lines or three or more planes veering from a
typical point, or inside of two planes separating from a typical line.

Types of Angles

Coordinates
One of an arrangement of numbers that decides the position of a point. One and only
one coordinate is required if the point on a line, two are needed if the point is in a
plane, and three in the event that it is in space.
