Does a rectangle have rotational symmetry?
Understand the Problem
The question is asking whether a rectangle exhibits rotational symmetry, which involves determining if the shape looks the same after being rotated by certain degrees (typically 180 degrees for rectangles). We know that a rectangle has rotational symmetry of order 2, meaning it can be rotated 180 degrees and still appear the same.
Answer
A rectangle has rotational symmetry of order 2.
The final answer is that a rectangle has rotational symmetry of order 2.
Answer for screen readers
The final answer is that a rectangle has rotational symmetry of order 2.
More Information
This means that a rectangle will map onto itself exactly twice during a 360° rotation, specifically at 180° and 360°.
Tips
A common mistake is to confuse the rotational symmetry of a rectangle with that of a square. A square has an order of 4.
