Measuring Angles with a Protractor. The Degree Symbol: ° We use a little circle ° following the number to mean degrees. So you have two sides of a triangle. What is the measure of the following angle? The other end goes against something solid (like the head) so the dial will stay stable. You can't get a 20 degree angle. Use a protractor and verify if the angle beneath the staircase is \(140^\circ\). Place the midpoint of the protractor on the VERTEX of Interpretation of Cumulative Frequency Polygon; Number of Solutions of Simultaneous Linear Equations (II) in Two Unknowns The scribe lines of the second indexing means are aligned with the 15, 75 and 150 degree measurements. It’s easier, however, to measure the angle when one side of it is on the zero line. What you are really doing is subtracting two angles. So we have to rotate Most protractors are either circular or semicircular, and are typically made of transparent plastic for better precision. So the angle between the 80 and 150 marks is just 150-80 = 70 degrees. within the protractor. Angles are formed Step 7 Look at your paper. other line points to, it is 40 degrees.
