    This is a standard construction according congruent theorem SAS:

    1. Draw the angle.
    2. Determine on the legs of the angle the length of the sides. This will give you the points A and C.
    3. Connect A and C.

    4. The midpoint M of the circle is the point of intersection of 2 parallels to the legs of the angle, distance 2 cm.
    5. Draw the circle.
