2. Difference between ‘postulate’ and ‘axiom’ is

 
 
 
 

3. ‘Lines are parallel if they do not intersect’ is stated in the form of

 
 
 
 

4. To solve the equation a – 20 = 15, we use Euclid’s …… axiom.

 
 
 
 

5. If a straight line falling on two straight lines makes the interior angles on the same side of it, whose sum is 120°, then the two straight lines, if produced indefinitely, meet on the side on which the sum of angles is

 
 
 
 

6.

Assertion (A): In the given figure, If ∠BOD = ∠AOC,
then ∠BOC = ∠AOD
Reason (R): Things which an double of same things and equal to one another

 
 
 
 

7. Assertion (A): A, B, C, D are 4 friends. A’s age is half of B’s age and C’s age is half of D’s age. If the ages of A and C are equal, then B and D will be of same age.
Reason (R): Things, which are double of the different things, are equal to one another.

 
 
 
 

8. Mehul is of same age as Tanya. Charis is also of same age as Tanya. The Euclid’s axiom that illustrates the relative age of Mehul and Charis is
