The large hexagonal box of constructive triangles which constructive triangles which contains:
One yellow equilateral with black lines on all sides.
Three yellow isosceles obtuse triangles with a black line on the side opposite to the obtuse angle. When the black lines on these triangles are mapped with those on the large equilateral triangle, they form a hexagon in which the equilateral triangle is inscribed.
Three yellow isosceles obtuse triangles, equal to the three mentioned above and black lines on the two equal sides. When the lines are mapped, the triangles form an equilateral triangle equal to that mentioned above.
Two red isosceles obtuse triangles, equal to both sets of yellow isosceles obtuse triangles described above, and having a black line on the side opposite to the obtuse angle. When these lines are mapped, the triangles form a rhombus.
Two gray isosceles obtuse triangles, equal to the yellow isosceles obtuse triangles and to the two red isosceles obtuse triangles described above. Each gray triangle has a black line on one side. When these lines are mapped, the triangles form a parallelogram
