if a=b, then a-c= b-c

Front 19

multiplication property of equality

Back 19

if a=b, then ac= bc

if a=b, then a-c= b-c

Front 24

multiplication property of equality

Back 24

if a=b, then ac= bc

Front 25

division property of equality

symmetric property of equality

Back 27

if a = b, then b = a

Front 28

transitive property of equality

Back 28

if a = b and b = c, then a = c

reflexive property of segment congruence

Back 30

for any segment AB, (AB) is congruent to (AB)

Front 31

symmetric property of congruency

Back 31

if (AB) is congruent to (CD), then (CD) is congruent to (AB)

Front 32

transitive property of congruency

Back 32

if (AB) is congruent to (CD), and (CD) is congruent to (EF), then (AB) is congruent to (EF)
