3.1 parallel lines crossed by transversal Flashcards
a line that intersects 2 or more co planar lines at different points
transversal
lie on the same side of the transversal
corresponding angles
nonadjacent angles that lie on opposite sides of the transversal between the intersected lines
alternate interior angles
lie on the same side of the traversal between the intersected lines
consecutive interior angles
lie on opposite sides of the transversal outside the intersected lines
alternate exterior angles
lie on the same side of the transversal outside the intersected lines
alternate exterior angles
lie on the same side of the transversal outside the intersected lines
consecutive exterior angles
are any lines in the same plane that do not intersect
parallel lines
uses boxes and arrows to show the structure of a logical argument
