Geometry 2.1Name and Classify Angles
Learning Target: I can name and classify the various types of angles as well as identify congruent
angles.[G.CO.1]
angle - consists of 2 different rays with the same endpoint.
C
AB
1
- the rays are the of the angle
- the endpoint is the of the angle

Classifying angles (use the degrees)- there are 4 different kinds of angles
2. Name all the angles in the diagram. Tell whether each angle appears to be acute, obtuse, right or straight.
Angle Addition PostulateIf P is in the interior of ∠RST,
then
3.

4. Given that m∠LKN = 145̊ find m∠LKM and m∠MKN.Write an equation and show your work!!
5. Given that m∠KLM is a straight angle, find m∠KLN.
Two angles are congruent if they have the same measure.
6. Identify all pairs of congruent angles in the diagram.
7. In the diagram, m∠P = 84˚, m∠PQR = 130˚, and m∠S = 121˚. Find the other angle measures in the diagram.
