Parallel Lines
Parallel Lines and Transversals
Question | Answer |
---|---|
Parallel | Coplanar lines that do not intersect. |
Perpendicular | Coplanar lines that intersect at a right angle. |
Oblique | Coplanar lines that intersect (but not at a right angle). |
Skew | Lines that do not intersect and are not in the same plane (noncoplanar). |
Transversal | A line that intersects two or more lines in a plane at different points. |
Corresponding Angles | Angles that are on the same side of the transversal and the same side of the parallel line. |
Consecutive Angles | Angles that are on the same side of the transversal and inside/outside the two lines. |
Alternate Interior | Angles that are on opposite sides of the transversal and inside the two lines. |
Alternate Exterior | Angles that are on opposite sides of the transversal and outside the two lines. |
