Answer

Join CE and AC.

In the figure (1) given below, BC || AE and CD || BE. Prove that area of ∆ABC= area of ∆EBD. Theorems on Area, ML Aggarwal Understanding Mathematics Solutions ICSE Class 9.

From figure,

∆ABC and ∆EBC lie on same base BC and between same parallel lines BC and AE.

∴ area of ∆ABC = area of ∆EBC ……. (i)

From figure,

∆EBC and ∆EBD lie on same base BE and between same parallel lines CD and BE.

∴ area of ∆EBC = area of ∆EBD ……. (ii)

From (i) and (ii), we get

area of ∆ABC = area of ∆EBD.

Hence, proved that area of ∆ABC = area of ∆EBD.
