Repeating Figures and Symmetries

How can tessellations be made with repeating figures?

What four types of symmetry do you look for in repeating figures?

Repeating figures

In most cases, repeating figure tessellations are easy to recognize. Pick out the shape, polygon, polygon unit, or shape that is repeated or rotated.

What is the repeated figure?

Consider color and pattern.

Translation

When a figure is translated, it is moved or slid.

RotationWhen a figure is rotated, it is

turned by degrees.

ReflectionReflection symmetry is also known

as line symmetry.

Vertical line symmetry Horizontal line symmetry

Glide Reflection

Your figure is translated and then reflected in a glide reflection.
