The correct options are
A ΔAIN
C ΔPIN
D ΔAIP
If a triangle and a parallelogram are on the same base and between the same parallel lines, the area of the triangle is equal to half the area of the parallelogram.
ΔAIN,ΔPIN,ΔAIP,ΔPAN
and parallelogram PAIN are on the same base and between the same parallel lines.
∴ar(ΔAIN)=ar(ΔPIN)=ar(ΔAIP)=12ar(PAIN)
