In the given figure, ABCD is a parallelogram. P and Q are any two points in AB and BC respectively. Area of Δ ADQ= ___
(i)ABCD is a ||gm (given)
(ii) areaΔADQ=12Area ||gm ABCD
(Area of a triangle is half the area of ||gm if they are on the same base (AD) and between the same ||'s)
(iii) areaΔDPC=12Area ||gmABCD
(Area of a triangle is half the area of ||gm if they are on the same base (DC) and between the same parallels)
(iv)∴areaΔADQ=areaΔDPC
