Reflexive Property of Congruence
A geometric figure is congruent to itself.
Right Angle
Angle whose measure equals 90 degrees.
Congruent Segments
Segments with equal lengths.
Midpoint
Point that divides a segment into two congruent segments.
Perpendicular Lines
Lines (or parts of lines) that intersect to form a right angle.
Congruent Angles
Angles with equal measures.
Segment Bisector
Line (or part of a line) that intersects the segment at its midpoint.
Supplementary Angles
Two angles with measures that have a sum of 180 degrees.
Right Triangle
Triangle that contain a right angle.
Transitive Property of Congruence
If one geometric figure is congruent to a second geometric figure, and the second geometric figure is congruent to a third geometric figure, then the first geometric figure is congruent to the third geometric figure.
Complementary Angles
Two angles with measures that have a sum of 90 degrees.
Angle Bisector
Ray that divides an angle into two congruent segments.
Perpendicular Bisector
Line (or part of a line) that is perpendicular to a segment at its midpoint.
Linear Pair
Two adjacent angles whose non-common sides are opposite rays and form supplementary angles.
