Points that lie on the same line

Points that lie on the same plane 

Two rays that have a common endpoint and form a line 

are two angles in the same plane with a common vertex and a common side

is a pair of adjacent angles whose non-common sides are opposite side 

are two angles whose measures have a sum of 90 

are two angles whose measure have a sum of 180

are 2 non-adjacent angles formed by two intersecting pairs 

lie on the same sides of the transversal t 

are non-adjacent angles that lie on the opposite sides of transversal t between lines R and S 

lie on the opposite sides of the transveral T outline R and S

angles are consecutive interior angles lie on the same side of the the transveral T between R ans S 

a point in the middle of a line with 2 endpoints 

a ray that divides an angle into two congruent angles
