Q. 15 B
In the trapezium ABCD, AB || DC and AB = 7 cm and DC = 5 cm. The midpoints of AD and BC are E and F respectively, the length of EF is
A. 5 cm
B. 7 cm
C. 6 cm
D. 12 cm
Answer :
Since AB||DC and E and F are midpoints of AD and BC,
By using the theorem:-
The line segment joining the midpoints of two side of a triangle is parallel to the third side and equal to half of it, we get
⇒ AB||CD||EF
