What you really need to know!
Angles that have the same measure are called congruent angles.
![Page 5: Lesson 10-3 Pages 422-425](https://reader036.fdocuments.net/reader036/viewer/2022062408/56813246550346895d98b8d4/html5/thumbnails/5.jpg)
Two angles are supplementary if the sum of their measures is 180.

Two angles are complementary if the sum of their measures is 90.

What you really need to know!
When two lines intersect, they form two pairs of opposite angles called vertical angles, which are always congruent.

Classify the pair of angles as complementary, supplementary, or neither.
Example 1:
128° 52°
![Page 11: Lesson 10-3 Pages 422-425](https://reader036.fdocuments.net/reader036/viewer/2022062408/56813246550346895d98b8d4/html5/thumbnails/11.jpg)
Classify the pair of angles as complementary, supplementary, or neither.
Example 2:
yx
![Page 12: Lesson 10-3 Pages 422-425](https://reader036.fdocuments.net/reader036/viewer/2022062408/56813246550346895d98b8d4/html5/thumbnails/12.jpg)
Example 3:
Angles PQS and RQS are supplementary. If m PQS = 56°, find m RQS.
180° - 56° = m RQS
124° = m RQS

Example 4:
The rectangle shown is divided by a diagonal. Find the value of x.
70°x 90° - 70° = x
20° = x
