State true or...
Question
State true or false:
In the given figure, E is mid-point of AB and DE meets diagonal AC at point F. If ABCD is a parallelogram and area of △ADF is 60cm2
DF:FE is 2:1
If true enter 1 else 0

Solution
ABCD is a parallelogram, DC is parallel to AB So,∠CAB=∠ACD ∠AFE=∠DFC (Vertical angles are always equal) &, ∠AFE=∠DFC So,DFC EFA DF/FE=DC/AE DC/12DC=2/1
