I can measure and create angles of a given measure by using a protractor. I can classify types of angles by their measurement.
3
Angle – a figure formed by two rays, or sides, with a common endpoint called the vertex. Interior angle – set of all points between the sides of the angle. Exterior angle – set of all points outside the angle.
4
Postulate 1-3-1 Given line AB and a point O on line AB, all rays that can be drawn from O can be put into a one-to-one correspondence with the real numbers from 0 – 180. Protractor Postulate
