WebHow to Label Angles There are two main ways to label angles: 1. give the angle a name, usually a lower-case letter like a or b, or sometimes a Greek letter like α (alpha) or θ (theta) 2. or by the three letters on the shape that define the angle, with the middle letter being where the angle actually is (its vertex). WebConstructing a 120-degree angle requires that we put two 60 degree angles together. We can actually use the same construction used in example 1 to prove that the angles of an equilateral triangle were equal to one-third of a straight line. In this case, the angle DAB consists of two smaller angles, DAC and CAB.

WebSo once again, 10, 20, 30, 40, 50, 60, 70, 80, 90-- that gets us to a right angle. Then we'll start getting into obtuse angles, 100, 110, 120, 130, 140, 150. And just to make sure that blue arc is measuring this angle right over here, not the outer one. And let me move the protractor out of the way so we can get a good look at it. WebExplanation: For sec 120 degrees, the angle 120° lies between 90° and 180° (Second Quadrant ). Since secant function is negative in the second quadrant, thus sec 120° value = -2 Since the secant function is a periodic function, we can represent sec 120° as, sec 120 degrees = sec (120° + n × 360°), n ∈ Z. ⇒ sec 120° = sec 480° = sec 840°, and so on.
