Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
The amount of rotation between two rays that share a common endpoint, measured in degrees or radians.
Opening a door wider makes a bigger angle; a corner of a book is 90°.
Example 1
easyTwo angles are supplementary. One measures 115°. Find the other.
Example 2
mediumTwo parallel lines are cut by a transversal. One of the alternate interior angles measures 72°. Find all eight angles formed.
Example 3
easyTwo angles are complementary. One measures 37°. Find the other.
Example 4
mediumAn exterior angle of a triangle measures 124°. One remote interior angle measures 47°. Find the other remote interior angle.
