definition of congruent segments
If segment AB is congruent to segment BC, then AB = BC.
reflexive property
AB = AB
symmetric property
If 6 = x, then x = 6.
transitive property
If a = b, b = c, then a = c.
definition of congruent angles
If angle ABC is congruent to angle DEF, then their measures are equal.
Midpoint Theorem
If A is the midpoint of segment BC, then segment BA is congruent to segment AC.
definition of congruent segments
If DE = EF, then segment DE is congruent to segment EF.
definition of congruent angles
If the measure of angle XYZ is equal to the measure of angle ABC, then angle XYZ is congruent to angle ABC.
