Question

Please answer the questions..

Answer 1

1) Name two Quadrilateral whose angles are congruent.

→ Square and Rectangle.

Square and Rectangle have congruent (equal) angles as each angle is of 90°

2) How many sq. m are in 1 hectare?

→ There are 10,000 m² in 1 hectare. 1 hectare us denoted as ha.

3) Is zero a rational number? Give reasons for your answer.

→ Yes zero is a rational number. A rational number can be written in p/q form where q should not be equal to 0. Since, 0 can be written as 0/1, 0/2, 0/3..... and so on, it is a rational number.

4) Find the value of $(-1)^{2095}$

→ Anything raised to the power 1 is 1 itself. Now, since it is -1, if the powers are even, then the outcome would 1 but if power is odd, then outcome would be -1. Since, 2095 is odd, answer is -1

Answer 2

1. square and rectangle

2. 10000 sq m in 1 hectare

3. yes as we write it as 0/1… 0/2... 0/3 etc.

4. -1 as 2095 is odd
