 parallel lines dont intersect transversal line that intersects the parallel lines interior angles angles inside of parallel lines exterior angles angles outside of parallel lines alternating interior angles interior angles; on opposite sides of the transversal and both inside the parallel lines (3,5); same number of degrees alternating exterior angles exterior angles; on opposite sides of the transversal and both outside the parallel lines (1,7); same number of degrees corresponding angles in the same position on the parallel lines in relation to the transversal (1,5); same number of degrees perpendicular lines intersect in form of "plus sign" and form right angles vertical angles intersect in form of "x" (numbered clockwise starting on left- 1=3, 2=4) adjacent angles next to each other (measure of largest angles=measure of first angle + measure of second angle) Authorearthgrl_5 ID13485 Card SetPreAlgebra Chapter 10 Descriptionchapter 10 Updated2010-04-07T21:23:09Z Show Answers
