Measure Angles
If two noncollinear rays have a common endpoint, they form an angle. The rays are the sides of the angle. The common endpoint is the vertex. The angle at the right can be named as ∠A, ∠BAC, ∠CAB, or ∠1.
8
Example:
a. Name all angles that have R as
a vertex.
b. Name the sides of ∠1.
9
Congruent Angles
Angles that have the same measure are congruent angles. A ray that divides an angle into two congruent angles is called an angle bisector. In the figure, PN is the angle bisector of ∠MPR. Point N lies in the interior of ∠MPR and ∠MPN ≅ ∠NPR.
10
Example:
Refer to the figure on the right.
If m∠MPN =
2x + 14 and m∠NPR = x + 34, find x and
find m∠NPR.

ALGEBRA
In the figure QP and QR are opposite
rays.
QS bisects ∠PQT.
If m∠PQT = 60 and m∠PQS = 4x + 14, find the value of
x.
