In my photo, you can see the detailed geometric structure of the leaf. It’s made up of trapezium which fit together. There are different kinds of trapezium; a right-angled trapezium which has two adjacent right angles, an acute is the same but with two adjacent acute angles, an obtuse trapezium has one acute and obtuse angle on its longer base. You can also see the parallel veins of the leaf running from the the centre to the edge. The green colour of the leave completes the pattern. Each colour in the sequence has an added letter starting with 3 for red, 4 for blue, and finally 5 for green.
