Learning and Development Interview Questions and answers for Mathematics-2.

1.What are all the rational numbers between √2 and √3? 

Answer: All rational number between √2 and √3  are 1.5, 1.6.

Explanation:

When dividing a rational number it results a number in either repeating decimals or terminating decimals. But

• √2 is an irrational number and it gives non-recurring and non-terminating decimals.

• Similarly, √3 is also an irrational number and it gives non-recurring and non-terminating decimals.

√2 = 1.414 (rounded to 3 decimal places)   and

√3 = 1.732 (rounded to 3 decimal places). 

This shows that there are multiple rational numbers between √2 and √3, for example, 1.5, 1.6

Therefore, all rational number between √2 and √3 are 1.5, 1.6.

2.What is a tangent?

Answer:  

A straight line that touches to the circle at any one point is called a Tangent and It is perpendicular to the radius line.

3.What is the difference between congruence and similarity?

Answer:  

If two figures have the same shape and size then those two figures are congruent to each other.

If two figures have the same shape but not the same size then those two figures are similar to each other.
