Here’s a few definitions to get us started!!!
Angle: it has two sides that share a common endpoint
Vertex: the point where the sides meet
A
BC
1
This angle can be named 4 different ways:
ABC, CAB, B, 1

Classify Angles
Classify the angle as acute, obtuse, right, or straight.
Answer: The angle is exactly 180°, so it is a straight angle.
![Page 9: Angle Relationships Power Point](https://reader033.fdocuments.us/reader033/viewer/2022061214/549c3bdfb47959aa318b469d/html5/thumbnails/9.jpg)

Classify Angles
Classify the angle as acute, obtuse, right, or straight.
Answer: The angle is less than 90°, so it is an acute angle.

Remember:
C comes before S in the alphabet and 90 comes before 180,
so that’s an easy way to remember complementary is 90
degrees and supplementary is 180 degrees.

Classify Angles
Classify the pair of angles as complementary, supplementary, or neither.
128° + 52° = 180°
Answer: The angles are supplementary.

Find a Missing Angle Measure
Angles PQS and RQS are supplementary.If mPQS = 56°, find mRQS.
Words The sum of the measures of PQS and RQS is 180°.
Variable Let x represent the measure of RQS.
Equation 56 + x = 180
