Discuss the concept of symmetry in tessellations.

• Symmetry in tessellations does not require repetition

• Symmetry in tessellations involves the balanced arrangement of shapes or patterns that repeat without gaps or overlaps, achieved through reflections, rotations, and translations.

• Symmetry in tessellations involves random placement of shapes without any order

• Symmetry in tessellations is only achieved through rotations

How can you determine if a figure has rotational symmetry?

• Rotate the figure less than 360 degrees and check if it looks the same in its original position.

• Measure the area of the figure

• Count the number of sides in the figure

• Rotate the figure more than 360 degrees and check if it looks different
