               1) If ABCD is a parallelogram, AE ⊥ DC and CF ⊥ AD. If AB = 10 cm, AE = 6 cm
               and CF = 5 cm, then AD is equal to:
               a. 10cm                          b.6cm                                  c. 12cm                                 d.
               15cm

               2) If E, F, G and H are the mid-points of the sides of a parallelogram ABCD,
               respectively, then ar (EFGH) is equal to:

               a. 1/2 ar(ABCD)           b. ¼ ar(ABCD)            c. 2 ar(ABCD)                         d.
               ar(ABCD)

















               3) If P and Q are any two points lying on the sides DC and AD respectively of a
               parallelogram ABCD, then:

               a. ar(APB) > ar(BQC)      b. ar(APB) < ar(BQC)    c. ar(APB) = ar(BQC)        d. None
               of the above

               4) If ABCD and EFGH are two parallelograms between same parallel lines and
               on the same base, then:

               a. ar (ABCD) > ar (EFGH) b. ar (ABCD) < ar (EFGH)     c. ar (ABCD) = ar (EFGH)
               d. None

               5) A median of a triangle divides it into two
               a. Congruent triangles      b. Isosceles triangles       c. Right triangles      d. Equal
               area triangles
