Def. Of congruent segments
Segment that has the same length
Definition of congruent angles
Angles that have the same measure
Def of angle addition postulate
A=B
A+C = B+C
Def of linear pair postulate
If two angles firm a linear pair, then they are supplementary
Def of segment addition postulate
If B is between A and C, then AB + BC= SC. If AB+BC=AC, then B I’d between A and C
Addition property
If a=b, then a+c=b+c
Distribive prop
If a(b+c) = ab+ ac
Reflective prop
A=a
Division prop
If a=b, then a/c = b/c
Substitution prop
If a=b, then a can be substituted for b in any equation or expression
Subtraction property
If a=b, the. a-c=b-c
Transitive prop
If a=b and b=c , then a=c
Congruent therom
If two angles are supplementary to the same angle then they are congruent
Converse: If we can see stars at night, then the skys clear
Original?
If the skys clear, then we can see stars at night
