• The line segment joining the mid-points of any two sides of a triangle is parallel to the third side and is equal to half of it.

• The line segment joining the mid-points of any two sides of a triangle is twice the third side.

• 18 cm

• 9 cm

• 16 cm

In the given figure, AE ll BF ll CG and D is the mid-point of CE . If AB = 4.2 cm, the length of BC is:

• 4 cm

In the given figure, AE ll BF ll CG and D is the mid-point of CE. Find the length of DF if CG = 7.8 cm
