parallel lines
2 lines on the same plane that never meet
what is the symbol for parallel lines
II
perpendicular
lines that intersect at 90 degrees
skew lines
lines that aren’t coplanar and never intersect
transversal
a line that intersects two or more other lines in a plane at different points
exterior angles
don’t get sqaushed (on the outside)
interior angles
get squashed (on the inside)
consecutive angles
interior angles on the same side
alternate exterior angles
exterior angles on opposite sides
alternate interior angles
interior angles on opposite sides
corresponding angles
one interior and one exterior on the same side
if two lines are parallel and cut by a transversal, then the following pairs of angles will be congruent…
