Study Notes

Naming Angles

Angles can be named using the vertex point when there are no other angles at the same vertex that may cause confusion.
Another method to name an angle includes using three letters, with the vertex being the center letter and the other two letters representing points on each ray.
A numeric label may also be used to name an angle if it is provided.

Bisect

The term "bisect" refers to the process of dividing something into two equal parts.

Perpendicular

Perpendicular lines intersect at right angles, creating a 90-degree angle between them.

Congruent

Two geometric shapes are considered congruent if they are the same shape and size.

Degrees

Degrees are the units used to measure the magnitude of an angle.

Parallel

Parallel lines are defined as lines that never intersect or meet, regardless of their length.

Vertex

The vertex is the point where two lines or rays meet, or it can refer to the peak or highest point of a geometric figure opposite its base.

Sides

In the context of an angle, the sides are the rays that form the angle.

Interior

The interior refers to the area found within a specified shape or figure.

Exterior

The exterior indicates the area that lies outside of a defined shape or figure.
