Question

determine the minimum rotation (in degrees) which will carry the following figure onto itself (where all sides and vertices will match up). round to the nearest tenth if necessary. degrees

Explanation:

Step1: Count the number of congruent parts

The figure has 2 congruent parts.

Step2: Use the formula for rotational symmetry

The formula for the minimum rotation angle is \(\frac{360^{\circ}}{n}\), where \(n\) is the number of congruent parts. Here \(n = 2\).

$$ \frac{360^{\circ}}{2}=180^{\circ} $$

Answer:

\(180\)
