Picture a cube turned inside out, with opposite sides bending and warping until they face each other and touch. This is a 3-torus. There are three types: this basic example, and then one twisted by 90 degrees and another twisted by 180 degrees. The family of 3-torus shapes can maintain...

In primary school, your child will learn about the following key geometric shapes: spheres, cones, prisms and pyramids. It’s worth knowing that geometrically prisms incorporate more solid shapes than you might traditionally think of as prisms. For example did you know that both a cube and a ...
What is the lateral area of a right rectangular prism that has rectangular bases measuring 3" \times 5" and a height of 6"? What 2D shapes make up the sides of a pyramid and a prism? What is the volume of a rectangular prism when the given area = 144 yd^2 and width = 11 yd?
A cube has 8 vertices. 7 are visible here and one is hidden. What are edges? Edges are the lines of a 2D or 3D shape. They are the lines that join the vertices (corner points) up to form shapes and faces. Although many shapes have straight lines and straight edges, there are shape...
Do you see how a builder takes the blueprint of a house and turns it into a real thing? All of this is possible because of the mathematical concept of the scale factor. The scale factor can be described as a parameter that is used to enlarge or reduce the sizes of shapes in two-...

Lines and corners are the basic building blocks of 2D shapes. These parts of a shape have some special names. Parts of a 2-D shape The line segments that make a 2D shape are called its sides. A corner at which two sides of a 2D shape meet is called a vertex. Two or more corners...
