Key concepts
3 concepts
- 1
An acute angle is less than 90°, a right angle is exactly 90°, and an obtuse angle is between 90° and 180°.
- 2
Vertical angles are opposite one another when two lines intersect and are always equal. Supplementary angles are adjacent and add up to 180°.
- 3
When parallel lines are intersected by a transversal, alternate interior angles, alternate exterior angles, and corresponding angles are equal.
