There is no additional information given. The only additional thing is the diagram. That's all that's given in the question bank.
My solution that it's a rhombus definitely makes a lot of sense.
Here's the proof that I came up with.
The question here refers to the classic parallelogram which has equal opposite angles and equal opposite and parallel sides. It doesn't mean special parallelograms like square, rectangle, rhombus and kite.
Summary:: If a circle can be inscribed in a parallelogram how will the parallelogram change? Explain.
It is a 10th grade math question in case you want to know.

So please, could you guide me on which books I should refer to for IPHO?
