Angle Relations
Angle relations and Transversals
Term | Definition |
---|---|
Transversal | A line that intersects two or more other lines |
Parallel Lines | Lines that are in the same plane but will never intersect |
Perpendicular Lines | Lines that are in the same plane and intersect and form a right angle |
Adjacent Angles | Angles next to each other that share a vertex and a side (line) These angles are supplementary. |
Vertical Angles | Angles that are opposite each other. These angles are congruent. |
Corresponding Angles | Angles that are in the same relative position when parallel lines are intersected by a transversal. These angles are congruent. |
Alternate Interior Angles | Angles are located inside the 2 parallel lines but are on opposite sides and ends of the transversal. They are diagonal of each other. These angles are congruent. |
Alternate Exterior Angles | Angles are located outside the 2 parallel lines but are on opposite sides of the transversal. These angles are congruent. |
Consecutive Angles | Angles that are located inside the parallel lines and are on the same side of the transversal. They are right next to each other with no line between them. These angles are supplementary. |
Supplementary Angles | Angles that when put together create a straight line which is 180 degrees. When parallel lines are intersected by a transversal, each obtuse and acute angles together are supplementary. |
