Line and Rotational Symmetry (5)

Describe translations, reflections and rotations of two-dimensional shapes. Identify line and rotational symmetries (ACMMG114)

LO: To identify line and rotational symmetries.
Know:

  • the definition of symmetry

Understand:

  • that objects can be rotated around the point to create symmetry

Do:

  • I can identify line and rotational symmetries.

Line Symmetry

A line of symmetry is a line which splits both sides of an object identically.

They can be horizontal, vertical or diagonal.

Rotational Symmetry

Rotational symmetry is when an object looks exactly the same after a rotation.

The number of times the object looks identical to the original picture is termed order.
