1. Find the symmetry in each shape. Draw in the symmetry lines where there is line symmetry, and tell what kind of rotational symmetry if there is rotational symmetry (use the fraction of a turn description for rotational symmetry).
a. The red cross has 1/4 turn symmetry as well as vertical, horizontal and diagonal line symmetry ( as shown)
b. The Canadian flag has vertical line symmetry only
c. This right turn arrow has horizontal line symmetry only
d. This 4-directional arrow has 1/4 turn symmetry as well as vertical, horizontal and diagonal line symmetry ( as shown)
e. This double arrow has 1/2 turn symmetry as well as horizontal and vertical line symmetry
f. This wavy flag shape has 1/2 turn symmetry, and no line symmetry.
g. This L-box shape has diagonal line symmetry only.
2. Which kind of symmetry do children learn first?
Line symmetry
3. If a shape has 1/4 turn symmetry, what order of rotational symmetry does it have? What angle of rotational symmetry does it have?
order 4 rotational symmetry and 90° rotational symmetry
