How To Measure Angles More Than 180 Degrees With A Protractor At Maria 1. draw a straight, horizontal line. use a ruler or the straight edge of your protractor to draw your reference line, or the first ray of your angle. make this line horizontal and any length you like. [6] the length of the line doesn’t matter. 2. place the hole or vertical line on your protractor at 1 end of the line. Add the measurement of the acute angle and 180. a reflex angle is more than 180 degrees, but less than 360. the acute angle you just measured plus 180 degrees will give you the degrees in the reflex angle. for example, if the reflex angle produces an acute angle of 18 degrees, that would mean the reflex angle is 198 degrees.
How To Measure Angles More Than 180 Degrees With A Protractor At Maria Overview of using a protractor to measure angles. place the protractor on the paper so the center hole is precisely on the vertex point of the angle you wish to measure. make sure one side of the angle lies along the zero line of the protractor (the line that usually has a 0 and 180 on it). note where the other side of the angle intersects with. In order to do this, we must identify where the top ray of the angle (segment lm in this example) intersects with the protractor and then read the measurements. notice that where segment lm crosses the protractor, there are two values: 60 and 120. since ∠mln is an acute angle (less than 90 degrees), you know that it can not equal 120 degrees. Step 2: position the protractor. to start, place the midpoint of the protractor (the small hole on the straight edge of the protractor) on the vertex (the point where the two lines meet) of the angle you want to measure. step 3: align the protractor. align one arm (line) of the angle with the zero line of the protractor. 00:00:04.000 in this lesson, we will learn on using a protractor to measure any angle that is greater than 180 degrees. 00:00:12.08 now, measure this angle, abc. 00:00:16.070 to measure this angle, we split this angle into 2 parts, by drawing a dotted line along bc. 00:00:24.050 by finding the sum of these 2 angles, we will get the angle abc. 00:00:29.120 now, we place the protractor, at the.

Step 1: find the vertex or center point of an angle. the vertex of an angle is the point of intersection where two rays (lines) meet. [2] locate the two lines and see where they meet. if the two lines of the angle do not touch then use the straight portion of the protractor to extend the lines until they meet to find the vertex.
