Question

Describe with words the planes of symmetry for a cube. Be specific on where they would be.

Answer 1

A plane of symmetry is an idea used to visualize how a 3-D object is symmetrical. You can imagine a plane of symmetry as a flat surface that cuts an object into two halves that are perfect reflections of each other. For an object to have a plane of symmetry, it must be 3-D (2-D objects have "lines of symmetry" instead) and symmetrical in at least one direction.

In geometry, a plane of symmetry is a 2-D surface that can cut a solid into two mirrored halves. Depending on the shape of the solid, the solid may have one or many planes of symmetry. For instance, a cube can be cut from corner to corner or through its center and form two symmetrical halve. The cube has nine symmetrical planes. Three planes lie parallel to the side squares and go through the centre(picture). Six planes go through opposite edges and two body diagonals.
