On the Diagonals of Billiardsdes are tangents of a confocal conic called caustic .. The variation of billiards in . with caustic . is called billiard motion. We recall and extend a classical result of Poncelet on the diagonals of billiards which envelope motion-invariant conics. Each billiard in . with caustic . is the flat pos

Circumparabolas in Chapple’s Porismthat the focal points of the parabolas in a certain one-parameter subfamily trace a straight line. The vertices of these parabolas move on rational cubic curves whose acnodes trace an ellipse centered at the poristic stationary triangle center which is the midpoint of the common incenter and the com

Integer Sequences from Circle Divisions by Rational Billiard Trajectoriese divisions into regions we derive a general formula for the number of division regions after each reflection. This will give rise to an integer division sequence. Restricting to the special cases . we show that the number of regions after each reflection . is beautifully related to Gauss’s arithmet
