How many planes for symmetry are there in a cube?
9 planes in Cube 3 Planes in Cuboid
How many planes of symmetry does a tetrahedron have?
I think it is only 3
What are 3 shapes that have rotation symmetry?
A circle, square, and a triangle all have rotational symmetry.
What type of shape has planes of symmetry?
If a two-dimensional shape has a line of symmetry, the shape is also symmetrical with respect to the plane passing through that line and perpendicular to the plane of the shape. For example, the floor of a rectangular room is symmetrical about a vertical plane halfway along the length (or breadth) of the room. Some 3-dimensional shapes will also have planes of symmetry. A sphere has infinitely many. An ellipsoid has three - one each along two of its axes. A cuboid, similarly, has 3. A torus (doughnut) has one. A pyramid with a n-gon base will have n vertical planes, and so on.
3 shapes with no lines of symmetry?
A scalene triangle, A trapezoid, an irregular pentagon.
