Which of the following statement are ture and which are false? Give reasons for your answers? (i) Only one line can pass through a single point. ltbr. (ii) There are an infinite number of lines which pass through two distinct points. (iii) A terminated line can be produced indefinitely on both sides. (iv) If two circles are equal, then their radii are equal. (v) In the given figures belows, if AB = PQ and PQ = XY, then AB = XY.

Answer»

SOLUTION :(i) False : SINCE any number of lines can PASS through a point.
(ii) False : This contradicts Postulate 1.
(iii) True : By Euclid's 2nd Postulate.
(iv) True : Superimposing the region of one CIRCLE on the other, we FIND them coinciding. So, their centres and boundaries coincide.
Thus, their radii will coincide i.e., they are equal.
(v) True : Euclid's 1st Axiom.
