Regular price $7.00 Sale

A set of 7 triangles that are about 1.75 x 1.75" (4.5 x 4.5 cm) each. These manipulatives are a perfect learning aid for teaching young children to distinguish different triangle types and general mathematics. They would be great for a classroom setting, homeschooling, or tutoring. Each triangle is a different color.

Included triangles and colors:

  • Equilateral Triangle (Red)
  • Isosceles Triangle (Green)
  • 45-45-90 Degree Triangle (Gray)
  • 30-60-90 Degree Triangle (Yellow)
  • Generic Scalene Right Triangle (Blue)
  • Scalene Acute Triangle (Black)
  • Scalene Obtuse Triangle (Brown)

The set includes 3 different right angle triangles and 2 non-right angle scalene triangles. All right angle triangles include the traditional small square on the right angle.

The triangles fit comfortably in hand and have a pleasant weight. They are laser cut from high quality 1/8" (3 mm) thick acrylic. Acrylic is a type of plastic and has a very smooth feel. We did not blunt the edges of any shapes.

Some colors are opaque and some are slightly translucent (a small amount of light may pass through, but you will not be able to distinguish any features of an object held behind the translucent colors).

Contact us for custom colors, sizes or bulk orders. We may also cut them from wood or other materials.

On a couple of the pieces, you may notice some slight surface flaws on one side caused by heat from the cutting laser. In particular, red and brown seem to have the surface flaw. It is much less common in the other colors. These small surface flaws DO NOT affect their ability as a learning aid nor are they very noticeable in person. See the close up photo of the red piece in the listing for an example of the worst case flaw.

We supply 1/8" birch plywood cutouts of the triangles here: Perfect if you wish to finish them yourself or are looking for a lower price point.

If looking for other geometric shapes, we have a basic and a complex geometric shapes listing, each containing 7 shapes.
