3. Rotations

Continue to next subchapter

Exercise 1 Page 563

Remember that the rotation should be counterclockwise.

Practice makes perfect

First, we draw a segment between any of the vertices of △ DEF and point P. We will start with F. Also, remember that the rotation should be counterclockwise.

Using a protractor, we draw a ray that makes an angle of 50^(∘) with PF

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

Repeating this procedure for the rest of the vertices, we can draw △ E'F'D'.

Finally, we will remove all unnecessary lines.
