#### Transcript of Planes Of Symmetry

What are planes of symmetry?

Planes of symmetry in: Cuboid

Planes of symmetry in: Cylinder

two of the faces of a cylinder are circles, circles have an infinite number of lines of symmetry, therefore cylinders have an infinite number of planes of symmetry

Planes of symmetry in: Cone, Sphere

Planes of symmetry in cones: infinite amount (base of a cone is a circle)

Planes of symmerty in Spheres: infinite planes of symmetry through the center of the sphere since you can cut it through the center and both parts are equal.

Planes of symmetry in: Regular Tetrahedron

It has three on each face from each vertex to the midpoint of the opposite side of the face.

Planes of symmetry

in: Cube

Three planes lie parallel to the side squares and go through the centre. Six planes go through opposite edges and two body diagonals

**PLANES OF SYMMETRY**

Planes of symmetry of a cube - Lines of symmetry - The Lines of symmetry divides a figure into two equal halves which are mirror images of each other. A Line can not divide a 3-D figure into two halves.

If it is a CUBE (a special type of cuboid), then it has nine planes of symmetry.

If it is a cuboid with length, width and height all different, then it has three planes of symmetry.

If it is a cuboid with two equal measurements (say width and length), then it has five planes of symmetry.
