Use each set of clues to make a solid

Make a cube.

◆ Use only three colours.◆ One blue square touches all

three red squares.◆ Another blue square

touches only two red squares.◆ A yellow square touches only one blue square.

This solid has five pieces.

◆ There is one square, which is clipped to all theother pieces.

◆ The isosceles triangles are red and green.◆ The edges of red shapes do not touch red shapes.◆ Only red, green and blue shapes are used.

Make at least two different solids with this set of clues.

◆ There are four pieces, all triangles.◆ There is only one red isosceles

triangle.◆ The blue and yellow triangles are

the same shape.◆ The other shape is green.
