What is order of rotational symmetry?
Understand the Problem
The question is asking about the concept of rotational symmetry, specifically how many times a shape can be rotated during a full 360-degree turn and still look the same. This involves understanding the characteristics of shapes and their symmetries.
Answer
The order of rotational symmetry is the number of times a figure matches its original image in one full 360-degree rotation.
The order of rotational symmetry is the number of times a figure matches its original image in one full 360-degree rotation.
Answer for screen readers
The order of rotational symmetry is the number of times a figure matches its original image in one full 360-degree rotation.
More Information
For example, a regular pentagon has an order of rotational symmetry of 5 because it can be rotated 72 degrees (360/5) at a time and still look the same in each of those positions.
Tips
A common mistake is assuming rotational symmetry is the same as reflective symmetry. They are different; rotational symmetry involves rotation, while reflective symmetry involves mirroring an image along an axis.
