Answer
(a)
(i) Parallel lines are
(ii) The pairs of intersecting lines are :
.
(iii) Concurrent lines are three or more lines passing through the same point.
∴ Lines are concurrent.
(b)
(i) False — Points A, B and D do not lie on the same straight line; therefore, they are not collinear.
(ii) False — From the figure, line AB and line ED do not intersect at C.
