Question

AI 10. If E, F, G and H are the mid-points of sides of a parallelogram ABCD
points of sides of a parallelogram ABCD then ar (EFGH) =
G
C
B
(b) 1/3ar (ABCD)
(a) ar(ABCD)
(c) 1/2ar(ABCD)
(d)1/4ar(ABCD)​

Answer 1

Answer:

(c) 1/2 ar( ABCD)

Step-by-step explanation:

When we join the mid points together they form triangles which are congruent to each other.

using congruent rules they can be proved congruent .

they form 8 congruent triangles out of which four are present inside EFGH.

so ar(EFGH)=4/8 ar(ABCD)

=1/2 ar(ABCD)
