[90/100 DoP] Doing some corrections for a math test I messed up on 😅. I’m not generally a great test-taker, but this time just I did worse than usual (but what can you do? 🤷‍♂️).

Shaded Area Ratios in Parallelograms: Practice Problems and Solutions| Geometry tricks

Que: In the parallelogram ABCD, where IJ is parallel to AD, and ED and HF are perpendicular to DC, what is the ratio of the areas of quadrilateral AGJI to triangle HFC?

Solution: In △ADE, GJ∥AE

So, ar(△GJD): ar(△AED)=GD²: AD²=9:25

ar(AEJG)= 25–9= 16 unit …………..(i)

△IEJ ~△GJD (Similar Triangles)

ar(△IEJ): ar(△GJD)=IJ²:GD²=4:9

ar(△IEJ)=4 unit ………(ii)

ar(△HFC)=ar(△GJD)=9 unit

ar(AGJI): ar(△HFC)=16–4: 9=12:9= 4:3
