You can rotate any subset of your diagram about a point. Here are the steps:

  1. Select ebd_Ebd175  the geometry to be rotated.
  2. Click the Rotation tool rotation icon  in the Construct toolbox, or select Rotation from the Construct menu.
  3. Click the screen to place your rotation point.
  4. In the data entry box presented, enter the angle of rotation.

The rotation of the selected geometry appears.

Notice all points on the rotated geometry are written as "prime", i.e. A becomes A'. If you rotate this geometry again, A' becomes A".
