Coterminal angles are angles that share the same initial and terminal sides. You can figure out what breed of angle you have by its measure. The reference angle of -155 degrees is degrees. example 1250 in Radians second input as a fraction of π: Example 27/5 π or 1.2 π then press the button "Find Quadrant" on the same row. Use this page to learn how to convert between mils and degrees. Usually, when a finer measure is needed we just add decimal places to the degrees. First we draw angle of 90 degrees using protractor. Here is a brief introduction to the four types of angles: Right angle. Relevance. Algebra -> Angles-> SOLUTION: What is the measure of an angle such that the sum of the measures of its complement and its supplement is 230 degrees?? And let me move the protractor out of the way so we can get a good look at it. 1 radian = 57.3R degrees. To find an angle coterminal to another you can do so by simply adding or subtracting any multiple of 360 degrees or 2 pi radians. In this illustration, only the positive angle is labeled with the proper degree measure. The angle made at the center of a circle by an arc whose length is equal to the radius of the circle is equal to One radian. radians = degrees × π / 180° Example. Not quite sure what this question means. From A and B strike two arcs of equal radius within the angle. $\endgroup$ – Mythomorphic Jun 10 '15 at 7:32 0 1.
