Describing Rotations

First, we draw a segment between any of the vertices of $\triangle ABC$ and point $P.$ We will start with $A.$

Using a protractor, we draw a ray that makes an angle of $30^\circ$ with $\overline{PA}$

Next, using a ruler or compass, we place a point along the ray so that $PA=PA'.$

Repeating this procedure for the rest of the vertices, we can draw $\triangle A'B'C'.$

Finally, we'll remove all unnecessary lines.
