2 angles formed by two lines and a transversal and occupy corresponding positions
corresponding 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 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
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
2 coplanar lines that don't intersect.
parallel lines
a line that intersects two or more coplanar lines at different points
transversal
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.
