Angles with a common
vertex, common side
and no interior points in
common
Adjacent angles

size
point
Two non-adjacent angles
formed when two lines
intersect
Vertical angles
Lines in the same plane
that don’t intersect
Parallel lines

degrees
Right angle
An Angle with measure greater
than 90 degrees
Obtuse Angle

segment into two equal
parts
midpoint

thickness that extends
indefinitely in all directions
Plane

common endpoint that are
non-collinear
Angle
Two lines that intersect
to form right angles
Perpendicular lines

of 180 degrees
Supplementary Angles
Non-coplanar lines that
do not intersect
Skew lines

bounded by two endpoints
Segment
To cut in two equal parts
bisect
