Description: Tetrapentos - Kadon Enterprises. These puzzles are laser-cut from transparent acrylic. The Lucite cut edges glow and make it easy to see the divisions between the individual pieces. The two colors differentiate the pieces by size. They are the shapes of four and five equilateral triangles joined, also known to mathematicians as tetriamonds and pentiamonds. ("Tetrapentos" comes from the Greek words for fours and fives.) See larger sets of polyiamonds in Kadon's Mini-Iamond Ring and Iamond Ring. Jacques' neat design of the symmetrical hexagon pattern in the 4" round tray has 5 extra unit triangles (black acrylic) that allow tiling of the most interesting designs. Start by placing the 5 triangles in a nice symmetrical array and then see if you can complete filling the circle with the rest of the pieces. Outside the tray you can form an even larger number of beautiful shapes. See a fantastic collection of 249 silhouette figures starting here on Jacques' website, along with detailed descriptions and explanations in French. Great fun for ages 6 to adult. Our hands-on set,
