### Quick Answer

**The common endpoint of the sides of an angle is called a vertex.** For example, triangles have three vertices, while squares have four. These common endpoints are often colloquially called corner points, though this may result in confusing them with angles.

Vertices are a common element of polygons, solid three-dimensional shapes and angles formed by rays or line segments. They are sometimes divided up into ears and mouths, when describing the vertices of irregularly shaped polygons. Ears are vertices which protrude past a certain boundary line, while mouths are vertices that lie inward of the boundary. Ear and mouth vertices make up anthropomorphic polygons.

Q:
## What are two non-collinear rays with a common endpoint?

A:

Full Answer >**An angle is formed by the union of two non-collinear rays that have a common endpoint.**This endpoint is the vertex of the angle, and the two rays become the sides of this angle. These two rays can form different types of angles.Filed Under: -
Q:
## What is a vertex angle?

A:

Full Answer >**A vertex angle refers to the angle that is formed by the two lines crossing at a vertex.**When asked for a vertex angle, the intended query is typically for the size of the angle in degrees or radians.Filed Under: -
Q:
## How do you bisect an angle?

A:Draw an arc on the vertex of the angle. Then draw two more arcs from the intersection of the previous arc and the two legs in the interior of the angle. Finally draw a straight line through the vertex and the intersection of the last two arcs.
