Study Notes
Angles Vocabulary
- Straight Angle: Measures exactly 180 degrees.
- Right Angle: Measures exactly 90 degrees.
- Adjacent Angles: Share a vertex and a common side.
- Supplementary Angles: Two angles that sum to 180 degrees; if adjacent, they form a straight angle.
- Complementary Angles: Two angles whose measures add up to 90 degrees; if adjacent, they form a right angle.
- Vertical Angles: Congruent angles formed opposite each other when two lines intersect.
- Perpendicular Lines: Lines that intersect at a right angle (90 degrees).
- Parallel Lines: Lines that are equidistant apart and will never meet or intersect.
- Transversal: A line that crosses two or more other lines, which may be parallel or non-parallel.
- Corresponding Angles: Angles that occupy the same relative position at each intersection formed by a transversal.
- Alternate Interior Angles: Nonadjacent angles located on opposite sides of a transversal between a pair of parallel lines.
- Alternate Exterior Angles: Nonadjacent angles located on opposite sides of a transversal outside a pair of parallel lines.
- Skew Lines: Lines that do not lie in the same plane and will never intersect.
