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.

What is the repeated figure?

Symmetries What are the four types of symmetries? Translation Rotation Reflection Glide Reflection

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

Rotation When a figure is rotated, it is turned by degrees.

Reflection Reflection symmetry is also known as line symmetry. Vertical line symmetryHorizontal line symmetry

Glide Reflection Your figure is translated and then reflected in a glide reflection

What kind of symmetry?

Identify the repeating figure.

Identify the repeating figure

How can tessellations be made with repeating figures? Repeating figures can be translated or rotated. What four types of symmetry do you look for in repeating figures? Translation Rotation Reflection Glide reflection
