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.

Vertical Angles

Non-adjacent angles formed by two intersecting lines and form congruent angles.
