5. The extra-square problem. Consider the following figure consisting of two triangles and 2 hexagons. Rearrange the triangles and hexagons as shown below. Notice that we have an extra white square. Explain where the extra white square come from.

Show that the triangle with vertices A(4, −7, 9), B(6, 4, 4), and C(7, 10, −6) is not a right- angled triangle.I need easy answer and clear

2. How can we explain the shapes of cans on supermarket shelves? (See page 311.) h Discs cut from squares Discs cut from hexagons

6. Make a sketch of an object or explain the object that could be created using the pattern displayed. You may use two of the triangles and one of each of the remaining shapes. The shape is 3D, but does not have to fully enclose a space. The shapes are to scale. 2x V
