  20. Identify which ones are trapeziums and which are not.

  21. Objective: To construct a perpendicular bisector of a line segment using paper folding.
    Procedure: Make a line segment on a paper by folding it and name it as PQ. Fold PQ to such a way that P falls on Q and thereby creating a crease RS. This line RS is the perpendicular bisector of PQ.
