If a triangle and a parallelogram are on the same base and between same parallels, then the ratio of area of the triangle to the area of parallelogram is

1. 1 : 3

2. 1 : 2

3. 3 : 1

4. 1 : 4

A median of a triangle divides it into two

1. triangles of equal area

2. congruent triangles

3. right triangles

4. isosceles triangles

In the adjoining figure, area of parallelogram ABCD is

1. AB × BM

2. BC × BN

3. DC × DL

4. AD × DL

In the adjoining figure, if l || m, AF || BE, FC ⊥ m and ED ⊥ m, then the correct statement is
