'''Alternate Angles''' are a pair of nonadjacent [[angle]]s on opposite sides of a transversal that cuts two [[line]]s.
'''Alternate Angles''' are a pair of nonadjacent [[angle]]s on opposite sides of a transversal that cuts two [[line]]s.
The angles can be both exterior or both interior to the two lines. '''Interior alternate angles''' are inside the [[parallel]] lines, and on opposite sides of the transversal. '''Exterior alternate angles''' are outside the parallel lines and on opposite sides of the transversal.
The angles can be both exterior or both interior to the two lines.
Alternate exterior angles are two angles formed when a transversal intersects a pair of lines. The angles are exterior angles on opposite sides of the transversal and do not have the same vertex. If the two lines intersected by the transversal are parallel, then the alternate exterior angles are congruent.
'''Interior alternate angles''' are inside the [[parallel]] lines, and on opposite sides of the transversal. '''Exterior alternate angles''' are outside the parallel lines and on opposite sides of the transversal.
