  • A line segment has definite length.
  • Three lines are concurrent if and only if they have a common point.
  • Two lines drawn in a plane always intersect at a point.
  • One and only one line can be drawn passing through a given point and parallel to a given line.

  • 8. 
    Select the wrong statement:

  • Only one line can pass through a single point.
  • Only one line can pass through two distinct points.
  • A terminated line can be produced indefinitely on both the sides.
  • If two circles are equal, then their radii are equal.

  • 9.
