Axioms are assumed
a. universal truths in all branches of mathematics
b. universal truths specific to geometry
c. theorems
d. definitions

Solution:

We know that

Axioms are acquired by man due to their day to day experiences

In order to prove it, no mathematical deduction is required

It is practically the starting point of reasoning

In all the branches of mathematics, it is assumed as universal truths.

Therefore, axioms are assumed as universal truths in all branches of mathematics .

✦ Try This: It is known that x + y = 15 and that x = z. Show that z + y = 15. Solve using Euclid’s axiom

Given, x + y = 15 --------- (1)

Also, x = z ------------------ (2)

We have to show that z + y = 15

Using Euclid’s second axiom,

If equals are added to the equals, the wholes are equal.

From (2),

x + y = z + y

From (1).

z + y = 15

Therefore, z + y = 15
