======[[Axiom 1: Things which are equal to the same thing are equal to one another|Things which are equal to the same thing are equal to one another]]======
======[[Axiom 1: Things which are equal to the same thing are equal to one another|Things which are equal to the same thing are equal to one another]]======
Comparison of geometric parameters to check for their equality, for example if an area of a triangle equals the area of a rectangle and the area of the rectangle equals that of a square, then the area of the triangle also equals the area of the square.
======[[Axiom 2 and 3: If equals are added or subtracted to equals, the wholes are equal|If equals are added or subtracted to equals, the wholes are equal]]======
======[[Axiom 2 and 3: If equals are added or subtracted to equals, the wholes are equal|If equals are added or subtracted to equals, the wholes are equal]]======
Euclid, magnitudes are objects that can be compared, added, and subtracted, provided they are of the “same kind.” Addition or elimination of equal parameters to equal quantities results in equal things, for which the relation of equality and the operation of subtraction make sense. In Euclid’s mathematics this relation and this operation apply not only to straight segments and numbers but also to geometrical objects.
======[[Axiom 4: Things which coincide with one another are equal to one another|Things which coincide with one another are equal to one another]]======
======[[Axiom 4: Things which coincide with one another are equal to one another|Things which coincide with one another are equal to one another]]======
From Euclid’s use of the word “equal” means “the same size”; two geometric figures are equal is justified by showing that one can be moved so that it coincides with the other.
======[[Axiom 5: The whole is greater than the part|The whole is greater than the part]]======
======[[Axiom 5: The whole is greater than the part|The whole is greater than the part]]======
Two individual things are connected together to form one entity then each of these two things that form a whole is smaller than the whole.
