answers.
(1) Only one line can pass through a single point.
(ii) A terminated line can be produced indefinitely on both the sides.
(iv) Iftwo circles are equal, then their radii are equal.
In Fig. 2.9. if AB=PQ and PQ=XY, then AB=XY.
Answer :-
(i) False
Reason : If we mark a point O on the surface of a paper. Using pencil and scale, we can draw infinite number of straight lines passing
through O.
(ii) False
Reason : In the following figure, there are many straight lines passing through P. There are many lines, passing through Q. But there is one and only one line which is passing through P as well as Q.
(iii) True
Reason: The postulate 2 says that “A terminated line can be produced indefinitely.”
(iv) True
Reason : Superimposing the region of one circle on the other, we find them coinciding. So, their centres and boundaries coincide.
Thus, their radii will coincide or equal.
(v) True
Reason : According to Euclid’s axiom, things which are equal to the same thing are equal to one another.
