Answer 2

Answer:

Euclid's first and second axioms are used.

Step-by-step explanation:

Euclid's first axiom : Equality is transitive.

i.e, If x = y, and if y = z, then x =z.

Euclid's second axiom : Addition of equals.

If x =y and a = b, then x + a = y + b.

Given:

BC = XD

C is the mid point of AB => AC = BC

D is the midpoint of XY => XD =YD

To prove :

AB = XY

Proof :

Since equality is transitive, we have

AC = BC = XD = YD

Also, using axiom of addition of equals we have

AB + BC = XD + YD

AC = XY

Hence proved.
