3.1 Parallel lines crossed by a transversal Flashcards
1
Q
Transversal
A
a line that intersects two or more coplanar lines at different points.
2
Q
Corresponding angles
A
lie on the same side of the transversal and on the same sides of the intersecting lines
3
Q
Consecutive interior angels
A
lie on the same side of the transversal between intersecting lines.
4
Q
Alternate interior angles
A
nonadjacent angels that lie on the opposite sides of the transversal between intersecting lines.
5
Q
Alternate exterior angles
A
lie on the opposite sides of the transversal outside the intersecting lines.
6
Q
consecutive exterior angels
A
lie on the same side of the transversal outside the intersected lines.
7
Q

A
any lines in the smart place that do not intersect
