AI Drawing Prompt Reference

Draw a square and a parallelogram to demonstrate the relationships among their side lengths, angles, and diagonals. Start by drawing a line segment between two vertices of the square, then find the perpendicular bisector of the segment. From the intersection point of the bisector and the segment, draw a circle that intersects the bisector at two points. Connect these points to the square's vertices to form another quadrilateral. Next, connect the midpoints of the square's diagonals and draw the diagonals of the parallelogram. Finally, label all angles and side lengths to showcase the geometric properties of the square and parallelogram.
