equals the sum of the remote interior angles | exterior angle |
one endpoint at a vertex of a triangle and the other on the line that contains the side opposite the vertex, so that the segment is perpendicular to this side | altitude |
an equilateral parallelogram | rhombus |
the point that divides a segment into two congruent segments | midpoint |
an angle whose measure is between 0 and 90 | acute angle |
a triangle with all sides congruent | equilateral triangle |
coplanar lines that do not intersect | parallel lines |
a parallelogram with four congruent angles | rectangle |
non-coplanar lines that do not intersect | skew lines |
two angles whose sum equals 180 degrees | supplementary angles |
two angles that share a common vertes but not a common side | vertical angles |
