The existence of the additive inverse (of ab).
Reflexive.
It is the additive property of equality, as the additive property of length, as applied to adjacent or parallel line segments.
Ab = 25 CD
Commutativity.
Identity

Ab = 25 CD
associative property
Commutativity.
The given form is ab = ba.This is multiplicative commutative property of equality.
Reflexive Property
yes because ab plus bc is ac
Identity
Difficult to tell when you cannot use parentheses. a*(b+c) or a(b+c) = ab + ac This is known as the distributive property of multiplication over addition.
no; commutative
the midpoint of AB.
