2 angles that are formed by 2 lines and a transversal. they lie opposite of each other on the transversal (up and down and left and right)they are in between the two lines. | alternate interior angles |
2 angles formes by 2 lines and a transversal. they lie opposite of each other on the transversal (up and down and left and right). they lie outside of the two lines | Alternate exterior angles |
two angles formed by two lines and a transversal. they are on the same side if the transversal and lie inside the two lines. | consecutive interior angles |
2 angles formed by two lines and a transversal and occupy corresponding positions | corresponding angles |
2 coplanar lines that don't intersect. | parallel lines |
2 planes that don't intersect | parallel planes |
if there is a line and a point not on the line, then there is exactly one point through the point parallel to the given line | parallel postulate |
if there is a line and a point not on the line, then there is exactly one line through the point perpendicular to the given line | perpendicular postulate |
2 lines that don't intersect and aren't coplanar | skew lines |
a line that intersects two or more coplanar lines at different points | transversal |
