Abcd Is Square E And F Are Respectively Mid Points Of Bc And Cd If R Is Mid Point Of Ef

ABCD is a square. E and F are respectively the mid – points of BC and CD. If R is the mid point of EF. Prove that : ar(△AER) =…


Since R is the mid point of EF .

∴ AR is the median in △AEF.

As, a median of a triangle divides it into two triangles of equal area .

 ∴ ar(△AER) = ar(△AFR)
