How many planes does a prism have? Geometric solids can have multiple planes of symmetry. For example, the rectangular prism below has three planes of symmetry. A cube has nine planes of symmetry. Three planes of symmetry are parallel to the surfaces and six planes of symmetry are diagonals.
How do you find the number of planes of symmetry for a prism?
There's a handy tip for working out the planes of symmetry in a regular prism like this. And that is if we consider the two-dimensional polygon at the base of the prism, then the number of planes of symmetry will be equal to the number of lines of symmetry plus one.
