Q:

What is the common end point of the sides of an angle?

A:

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.

The vertex is the common endpoint when two rays intersect to form an angle. The formed angle is named by using three points. One point is on each of the two rays, and the third is at the vertex point.

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.

To find the midpoint of a line segment, determine where their coordinates are on the x-y axis, and use the mean to find the point midway between each x and y endpoint. This provide an accurate midpoint, allowing for other mathematical functions.
