Tangram
Product Code : JL-LEP-10302
The Tangram (SKU JL-LEP-10302) is a seven-piece puzzle used to develop ideas of area, perimeter and pattern. The tangram set has two small, one medium and two large triangles, one square and one parallelogram. All three triangle sizes are similar right isosceles triangles, every angle is a multiple of 45 degrees, and the small triangle is the unit for comparing areas. Together the pieces form a square at least 114 mm across and 7 mm thick, in durable non-toxic plastic of at least six colours. JaincoLab manufactures it in India, made as per DepEd guidelines.
Specifications
The set is specified by pieces, angles, material, size and colours: 5 similar right isosceles triangles (2 small, 1 medium, 2 large), a square and a parallelogram, all angles 45, 90 or 135 degrees, non-toxic plastic, forming a square of at least 114 mm and 7 mm thick.
