The number of dimension, a point has
a. 0
b. 1
c. 2
d. 3

Solution:

We know that

A point marks a place and has no length, breadth and thickness

A point is devoid of three fundamental dimensions

Therefore, a point has 0 dimension.

✦ Try This: Bharathi is of the same age as Prabha. Nirmala is also of the same age as Prabha. State the Euclid’s axiom that illustrates the relative ages of Bharathi and Nirmala a. First Axiom, b. Second Axiom, c. Third Axiom, d. Fourth Axiom

It is given that

Age of Bharathi = Age of Prabha

Age of Nirmala = Age of Prabha

According to Euclid’s first axiom, the things which are equal to the same thing are equal to one another.

So using the Euclid’s first axiom

Age of Bharathi = Age of Nirmala

Therefore, Euclid’s first axiom can be used here.
