Parallel lines- lines that are coplanar and do not intersect
Perpendicular lines- lines that intersect at 90ᵒ angles
Skew lines- lines that are not coplanar and do not intersect
Parallel planes- planes that do not intersect
Transversal- line that intersects two coplanar lines at different points
Corresponding angles- two angles that lie on the same side of the transversal and the same side
of the two given lines
Alternate interior angles-two angles that lie on opposite sides of the transversal and inside the
given lines
Alternate exterior angles- two angles that lie on opposite sides of the transversal and outside
the given lines
Same-side interior angles-two angles that lie on the same side of the transversal and inside the
given lines
Perpendicular bisector (of a segment)-line perpendicular to a segment at the segment’s
midpoint
Distance (from a point to a line)-length of a perpendicular segment from the point to the line
