PLEASE ANSWER THEN I'LL MARK U BRAINLY 1. When measuring an angle on a protractor, where must the vertex be placed? 2. What is a statement that is accepted to be true without having to formally prove it? 3. What is the measurement of a straight angle?
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.
