Question

if c is the midpoint of ab and d is midpoint on ac then prove ad=1/4 ab

Answer 1

Given c is the midpoint of AB.
           AC = CB
or        AC = half of AB         (1)
                                             (by Euclid's axiom)
and D is the mid point of AC

         AD=DC
or      AD=half of  AC         (2)
on putting the value of AC from equation        (1)
