Rectangular Triangles
- A pair of yellow equilateral triangles with a black line along on of the sides.
- A pair of gray scalene right-angled triangles with a black line along the hypotenuse.
- A pair of green scalene right-angles triangles with a black line along the hypotenuse.
- A pair of yellow isosceles right-angled triangles with a black line along one of the two sides.
- A pair of green isosceles right-angled triangles with a black line along the longer side.
- A pair of yellow scalene right-angled triangles with a black line along the shorter side.
- One smaller red scalene right-angled triangle with a black line along the longer side.
- One red scalene obtuse-angled triangle with a black line along the side opposite the obtuse angle.
Blue Rectangular Box
- All the materials are blue with no black lines
- The number of triangles is reduced to the following:
A pair of equilateral triangles
A pair of isosceles right-angled triangles
A pair of scalene right-angled triangles
A smaller scalene right-angled triangle
A scalene obtuse-angled triangle
Triangular Box
- 1 large gray equilateral triangle without black lines.
- 2 green right-angled scalene triangles. Each is a half of the gray triangle, with the black lines along the equal sides.
- 3 yellow obtuse-angled isosceles triangles. Each is a third of the gray triangle with the black lines along the equal sides.
- 4 red equilateral triangles. Each is one fourth of the gray triangle with black lines on: one triangle along all the sides, three triangles along one side only.
Large Hexagonal Box
- 2 green right-angled scalene triangles. Each is a half of the gray triangle, with the black lines along the equal sides.
- 3 yellow obtuse-angled isosceles triangles. Each is a third of the gray triangle with the black lines along the equal sides.
- 4 red equilateral triangles. Each is one fourth of the gray triangle with black lines on: one triangle along all the sides, three triangles along one side only.
- One large yellow equilateral triangle with a black line along all sides.
