median of a triangle
segment from a vertex to the midpoint of the opposite side
altitude of a triangle
perpendicular segment from a vertex to the line that contains the opposite side
perpendicular bisector
line, ray, or segment that is perpendicular to the segment at its midpoint
if a point lies on the perpendicular bisector of a segment, then the point is ( )
equidistant from the endpoints of the segment
if a point is equidistant from the endpoints of a segment, then the point ( )
lies in the perpendicular bisector of the segment
if a point lies on the bisector of an angle, then the point is ( )
equidistant from the sides of the angle
if a point is equidistant from the sides of an angle, then the point ( )
lies on the bisector of the angle
if 2 lines are parallel, then ( )
all points on one line are equidistant from the other line
if 3 parallel lines cut off congruent segments on one transversal, then they ( )
cut off congruent segments on every transversal
a line that contains the midpoint of one side of a triangle and is parallel to another side ( )
passes through the midpoint of the 3rd side
the segment that joins the midpoints of 2 sides of a triangle ( ) and ( )
is parallel to the 3rd side; is 1/2 as long as the 3rd side
