Designed to boost confidence and grades!
Parallel lines - Answer: coplanar lines that do not intersect


Skew lines - Answer: noncoplanar; they are not parallel and do not intersect


Parallel planes - Answer: planes that do not intersect


Transversal - Answer: a line that intersects two or more coplanar lines at distinct points


Alternate Interior Angles - Answer: nonadjacent interior angles that lie on opposite sides
of the transversal


Same-Side Interior Angles - Answer: interior angles that lie on the same side of the
transversal


Corresponding Angles - Answer: lies on the same side of the transversal and in
corresponding positions


Alternate Exterior Angles - Answer: nonadjacent exterior angles that lie on opposite
sides of the transversal


Exterior Angle of a Polygon - Answer: an angle formed by a side and an extension of an
adjacent side


Remote Interior Angles - Answer: two nonadjacent interior angles


Slope - Answer: the ratio of vertical change to the horizontal change between any two
points
