HPI (Hansen Polygons, Inc.) is pleased to introduce its 2002 line of polygons for all occasions.

Among our more reasonably priced models are the Rhombus^®, the fun and sporty Kite^®, the budget-priced Trapezoid^®, the versatile Parallel-O-Gram^®, the ultra-dependable (though not very exciting) Square^®, and the ever-popular Rectangle^®.

Below is a feature list for all our best-selling 3- and 4-sided models. Help us fill in the blanks!

Remember, you can buy Equilateral Triangles from either our Equiangular Dept. or from our Isosceles Dept. Because of the large demand for Squares, we are currently looking for a dealer to take part of the customer load currently being handled by the Rectangle Dept. and the Rhombus Dept. If you are interested in selling Squares, please send your resume to E. Michael Hansen, c/o St. Albans School, Mount St. Alban, Washington, DC 20016-5095.
