PLEASE ANSWER THEN I'LL MARK U 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.

Question - 1 answer -: How to measure an angle with a protractor:Place the midpoint of the protractor on the VERTEX of the angle.Line up one side of the angle with the zero line of the protractor (where you see the number 0).Read the degrees where the other side crosses the number scale.Question - 2answer -:

An axiom or postulate is a statement that is accepted without proof and regarded as fundamental to a subject.

Question -3 answer -:

A straight angle is the same as half the circle and is 180° whereas a right angle is a quarter of a circle and is 90°. You measure the size of an angle with a protractor.
