Angle Relationships
Angle Relationships Vocabulary
| Term | Definition |
|---|---|
| Acute Angle | Angle whose measure is less than 90 degrees |
| Right Angle | Angle whose measure is equal to 90 degrees |
| Obtuse Angle | Angle whose measure is greater than 90 degrees |
| Complementary Angles | Two angles whose measure have a sum of 90 degrees |
| Supplementary Angles | Two angles whose sum equals 180 degrees |
| Vertical Angles | When the angles across from each other and have a sum of 360 degrees |
| Linear Pair | Formed when two lines intersect each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum should always equal 180 degrees |
| Adjacent Angles | Angles that share a side and a vertex |
| Alternate interior angles | The angles inside the parallel line that are on opposite sides of the transversal |
| alternate exterior angles | Angles that are outside a pair of parallel lines and on opposite sides of transversal |
| same-side interior angles | Two angles that are on the same side of the transversal line and on the interior of the two lines |
| same-side exterior angles | Two angles that are on the same side of the transversal line and on the exterior of the two lines |
| corresponding angles | When the angles are in the same position (they will be congruent) |
