    A1. Place the midpoint of the protractor on the VERTEX of the angle.

    A2. An axiom or postulate is a statement that is accepted without proof.

    A3. A straight angle is an angle with measure 180 degrees. It is called a straight angle because if there were an angle that had measure 180 degrees, the three points that form the angle would be in a straight line.
