What Is the Tri-Square Puzzle Used For?
Turning an equilateral triangle into a square with only four pieces is the dissection made famous by the English puzzle writer Henry Dudeney. Young pupils treat it as a shape puzzle: build the triangle, break it up, then find the square. Older students can use it to reason about area — since the same four pieces make both shapes, the triangle and the square must have equal areas, even though their perimeters differ. A package of 10 lets a teacher hand one puzzle to each pair or small group, making it a quick challenge for the start or end of a geometry lesson.
Frequently Asked Questions
Which shapes can the Tri-Square Puzzle make?
Two: an equilateral triangle and a square. The same four pieces form either shape when they are assembled correctly.
Why do the triangle and the square have the same area?
Because they are made from the same pieces. Rearranging pieces changes the outline but not the total area, which makes the puzzle a hands-on way to show that shapes of equal area can look quite different; the triangle’s perimeter is the longer of the two.
How many puzzles come in a package?
Ten. Each package holds 10 four-piece puzzles, enough for a group activity.
What details are needed for an export quotation?
Tell us the number of packages, the destination country and port or city, your preferred delivery terms (for example FOB or CIF), any packing or labelling needs, and the tender reference if there is one.
