Question

the following figure has potential lines of symmetry every

degrees.

Explanation:

Step1: Identify the figure

The figure is an equilateral triangle.

Step2: Recall the formula for rotational symmetry

For a regular polygon with \(n\) sides, the angle of rotational symmetry is \(\frac{360^{\circ}}{n}\).

Step3: Calculate for an equilateral triangle

An equilateral triangle has \(n = 3\) sides. So, \(\frac{360^{\circ}}{3}=120^{\circ}\)

Answer:

\(120\)
