Transversal • A transversal is a line thatcrosses 2 lines (mostlypararell) at 2 differentpoints.
Corresponding, alternate exterior, alternate interior and consecutive interior angles. • Correspondingangles are 2 angles in a transversal with 2 pararelllines, that are in thesame position. • Alt. Interior angles are 2 anglesthat are in theoppositesidebutinsidethe transversal withpararells. • Alt exterior angles are 2 oppositeangles in a trans. Withpararells. But in theoutside. • Sameside interior angles are 2 anglesthat share thesameside in the interior of a transversal with 2 pararelllines.
Corresponding:1,5 Alt interior: 3, 6 Alt. Exterior: 2, 7 Sameside: 4, 6 1 2 3 4 5 6 7 8

Trans. Porperty in lines • Pararell: If 2 pararelllines are pararelltoanotherliaswellthenall of them are pararell. • Perpendicular: If 2 perp. Lines are perpendicular toanother line, thentheyall are perpenducular.
