two dimensional
plane
a dot on both ends
named by its end points
the part of a line that consists of two points, called endpoints, and all points between them
segment
a dot on one end and an arrow on the other
named by its endpoint first and another point on the ray
the part of a line that consists of one endpoint and all the points of the line on one side of the endpoint
ray
a common endpoint and an arrow on both ends
named by the common endpoint and another point on each ray
rays with the same endpoint that lie on the same line
opposite rays
two rays with a common vertex (endpoint)
named by a single letter (vertex), number, or 3 points with the vertex in the middle
formed by two rays with the same endpoint
a side of the angle and the common endpoint is the vertex
angles
two angles across from each other formed by intersecting lines; they are always congruent
vertical angles
