PreAlgebra Chapter 10

dont intersect

line that intersects the parallel lines

angles inside of parallel lines

angles outside of parallel lines

interior angles; on opposite sides of the transversal and both inside the parallel lines (3,5); same number of degrees

exterior angles; on opposite sides of the transversal and both outside the parallel lines (1,7); same number of degrees

in the same position on the parallel lines in relation to the transversal (1,5); same number of degrees

intersect in form of "plus sign" and form right angles

intersect in form of "x" (numbered clockwise starting on left- 1=3, 2=4)

next to each other (measure of largest angles=measure of first angle + measure of second angle)
