question 19

what is the angle of rotational symmetry?

image of a snowflake

• 60°
• 45°
• 72°
• 300°

Explanation:

Step1: Identify the number of sides/sections

A snowflake (like a regular hexagon - shaped snowflake) has 6 equal - angled sections or "arms" (it's a regular hexagon - based figure, so the number of rotational symmetry positions \(n = 6\)).

Step2: Calculate the rotational symmetry angle

The formula for the angle of rotational symmetry \(\theta\) is \(\theta=\frac{360^{\circ}}{n}\), where \(n\) is the number of times the figure maps onto itself during a full rotation (\(360^{\circ}\)). Substituting \(n = 6\) into the formula, we get \(\theta=\frac{360^{\circ}}{6}=60^{\circ}\).

Answer:

\(60^{\circ}\) (corresponding to the option with \(60^{\circ}\))
