1
Q
is a line that intersects two or more coplanar lines at different points.
A
Transversal
2
Q
lie on the same side on the transversal and on the same sides of the intersecting lines.
A
Corresponding angles
3
Q
are nonadjacent angles that lie on opposite sides of the transversal between the intersected lines.
A
Alternate interior angles
4
Q
lie on the same side of the transversal between the intersected lines.
A
Consecutive interior anges
5
Q
lie on opposite sides of the transversal outside the intersected lines.
A
Alternate exterior angles
6
Q
lie on the same side of the transversal outside the intersected lines.
A
