Summary[edit]

Description
English: The envelope of a ladder (coloured lines in the top-right quadrant) sliding down a wall, and its reflections (other quadrants) is an astroid. Its midpoint (small disks) traces out a circular arc (thick white circle) while other points (triangle and square) trace out elliptical arcs (thin white ellipses). In the SVG file, hover over a ladder to highlight it.
