1
Q
P.O.E.
A
property of equality
2
Q
addition POE
A
if a=b, then a+c=b+c
3
Q
subtraction POE
A
if a=b then, a-c=b-c
4
Q
multiplication POE
A
if a=b then ac=bc
5
Q
division POE
A
if a=b and c does not equal 0, then a/c=b/c
6
Q
reflexive POE
A
for any real number a, a=a
7
Q
symmetric POE
A
if a=b, then b=a
8
Q
transitive POE
A
if a=b and b=c, then a=c
9
Q
substitution POE
A
if a=b! then A may be substituted for B in any equation or expression
10
Q
reflexive POC
A
any geometric shape is congruent to itself
11
Q
symmetric POC
A
if one geometry object is congruent to a second, then the second object is congruent to the first
12
Q
transitive POC
A
if one geometric object is congruent to a second, and the second object if congruent to a thisprd, then the first object is congruent to the third object
