AI Drawing Prompt Reference

Draw a rhombus and demonstrate its area calculation. Start by drawing one side of the rhombus and a circle with this side as the diameter. Find the intersection of the circle with a line perpendicular to this side to form the rhombus. Then, calculate the lengths of the diagonals, construct perpendiculars using midpoints, and use rotations and reflections to show the derivation of the area formula.
