SS9.4
Demonstrate understanding of line and rotation symmetry.

[C, CN, PS, V]

Indicators for this outcome
(a)

Observe and describe examples of line and rotation symmetry in situations relevant to self, family, or community.

(b)

Classify different 2-D shapes or designs made of 2-D shapes, according to the number of lines of symmetry.

(c)

Complete a 2-D shape or design given part of a shape or design and one or more lines of symmetry.

(d)

Determine, with justification, if a given 2-D shape or design has rotation symmetry about the point at the centre of the shape or design and, if it does, state the order and angle of rotation.

(e)

Identify a line of symmetry, or the order and angle of rotation symmetry, in a given tessellation.

(f)

Describe examples of the use and significance of line and rotation symmetry in First Nations and Métis art.

(g)

Analyze different transformations of 2-D shapes on the Cartesian plane and describe the type of symmetry, if any, that results.

(h)

Determine whether or not two 2-D shapes on the Cartesian plane are related by either rotation or line symmetry and explain.

(i)

Create or provide an art work (such as a painting or dance) that demonstrates line and rotation symmetry, and identify the line(s) of symmetry and the order and angle of rotation.
