Someone showed me this picture of a quadrilateral made by joining together five smaller quadrilaterals.

It made me think about special cases...

Could I draw a version of this image where all five of the smaller quadrilaterals are cyclic? I tried it out and have tried to capture what I did, and what the question was that it made me want to answer, in the video below:

Can you convince us that the largest quadrilateral is also cyclic?
