Which of the following is a true axiom?
A When A = C and B = C, then A = B because both are equal to C, Which supports the axiom:
Quantities equal to the same quantity are equal to each other.
B When A = D and B = C, then A = B because both are equal to C and D, Which supports the
axiom: Quantities equal to the same quantity are equal to each other.
C When A = C, B = E, and C = D, then A = B because both are equal to C, Which supports the
axiom: Quantities equal to the same quantity are equal to each other.
D When A = C and B = C, then A cannot equal B because both are equal to C, Which supports
the axiom: Quantities equal to the same quantity are not equal to each other. Correct Ans-A
