Question

. In figure, ABCD is a quadrilateral and DP || AC. Show that ar(AABP) = ar(ABCD).​

Answer 1

Step-by-step explanation:

From the figure we know that △ ACP and △ ACD lie on the same base AC between parallel lines AC and DP

It can be written as

Area of △ ACP = Area of △ ACD

By adding △ ABC to both LHS and RHS

Area of △ ACP + Area of △ ABC = Area of △ ACD + Area of △ ABC

So we get

Area of △ ABP = Area of quadrilateral ABCD Therefore, it is proved that ar (△ ABP) = ar (quad. ABCD).

Hope this is helpful for you.
