Question

It is known that, if $x+y=10$, then $x+y+z=10+z$. The Euclid’s axiom that illustrates this statement is:

• A. First axiom
• B. Fourth axiom
• C. Third axiom
• D. second axiom

Answer 1

The correct option is D second axiom

If equals are added to equals, the wholes are equal, which is second axiom of Euclid's.
Hence, option (b) is correct.
