Symmetry

What is the angle of rotation for a regular pentagon?

• 60 degrees

• 72 degrees

• 90 degrees

• 108 degrees

Define rotational symmetry.

• Rotational symmetry exists when a shape can be rotated around a central point and still look the same at certain angles.

• Rotational symmetry occurs when a shape can be reflected across a line and remain unchanged.

• Rotational symmetry is when a shape can be translated along a path and appear identical.

• Rotational symmetry is the property of a shape that allows it to be stretched without changing its appearance.

How many lines of symmetry does a regular hexagon have?

• 4

• 5

• 6

• 8

What is the relationship between the number of lines of symmetry and the order of rotational symmetry?

• In regular polygons, the number of lines of symmetry is equal to the order of rotational symmetry.

• The number of lines of symmetry is always greater than the order of rotational symmetry.

• The number of lines of symmetry is always less than the order of rotational symmetry.

• There is no relationship between the number of lines of symmetry and the order of rotational symmetry.

What is the order and angle of rotation of a flower with 6 identical petals?
