a. Describe the different types of planes of symmetry
and axes of symmetry of a regular octahedron.
b. How many planes and axes of symmetry does a regular
octahedron have?
c. Make a sketch and compare the symmetry properties
of a regular octahedron and a cube.

a)The planes ands axes of symmetry go through the faces, edges, and vertices of the octahedrons.
b)There are 13 planes and axes of symmetry
3 go through opposite faces, 4 go through opposite vertices, 6 go through the midpoints of opposite edges
c)The symmetry properties of cubes and regular octahedron are the same
