The is the common endpoint.
The rays are called the of the angle.
An angle can be formed by , but they should still be considered parts of rays.

Naming angles:
When there is only angle at a given vertex the angle can be named by the vertex.
When there are several angles with the same vertex the angle is named by a point from each with
the vertex point in the of the name.
[pic]can be named or
[pic]can be named or
The of an angle is the amount
of openness of the of the angle.
The “measure of an angle 1” is written as:
An angle is measured in
The of an angle is the region that contains all points between the two rays.
The of an angle is the region containing all the points outside of the angle.
Postulate 1-7: Protractor Postulate: Consider [pic]and a point A on one side of [pic]. Every ray of the form [pic]can be paired with a real number from 0 to 180.
Measuring an angle with a protractor:
