Question

what is the minimum number of degrees that a square can be rotated before it carries onto itself? a. 360° b. 45° c. 90° d. 180°

Explanation:

Step1: Understand rotational symmetry

A square has rotational symmetry. The total rotation for a full circle is \(360^{\circ}\).

Step2: Divide by the number of sides

A square has \(4\) equal sides. The formula for the angle of rotational symmetry is \(\frac{360^{\circ}}{n}\), where \(n\) is the number of sides. For a square, \(n = 4\). So, \(\frac{360^{\circ}}{4}=90^{\circ}\).

Answer:

C. \(90^{\circ}\)
