The degree of an angle can be determined using the tangent function. From one ray of the angle, draw a perpendicular line until it intersects the other ray of the angle. Measure the length of the first ray (A) and the perpendicular line (B) and set as a ratio of B/A. This ratio is equal to the tangent of the angle.

How do you find the degrees of the angles of shapes?
Use a protractor or use the formula: (n-2)*180 = sum of degrees whereas 'n' is the number of sides of the shape or polygon

Can you measure 20 degrees on a protractor?
Yes, you can measure 20 degrees on a protractor. A protractor typically has degree markings ranging from 0 to 180 degrees and sometimes up to 360 degrees. To measure 20 degrees, align the protractor's baseline with one side of the angle, then find the 20-degree mark on the curved edge. Ensure the center point of the protractor is at the vertex of the angle for an accurate measurement.

How do you figure out the degree of a shape using a protractor?
You can find out the degrees of the angles of shape shape by following these instructions. First you line up the bottom line of the protractor onto a side of a shape. The corner of the shape should be on the tiny dotlike thing in the middle of the bottom line of the protractor. Next, you find out if the angle is obtuse (larger than a right angle), acute (smaller than a right angle), or right. If it's obtuse, you know that it's larger than 90 degrees. You should look at the larger number the other line is pointing at. If it's acute, find you the angle by finding out which number the other line is pointing at. If you think it's a right angle, see if the line's pointing at another number. Otherwise, it's a right angle.
How do you find angle measures without a protractor?
use the sun and silhoutte
How do you find a reflex angle?
A reflex angle is generally larger that 90 degrees. To find an angle if the diagram is in scale use a protractor is not you would use geometry to find that angle unless the shape is regular such as a square we you know that every angle inside a square equals 90 degrees. So its all depends on the situation.
How do you measure a reflex angel with 180 protractor?
To measure a reflex angle using a 180-degree protractor, first position the protractor so that its baseline aligns with one side of the angle, ensuring the center point is at the vertex. Measure the smaller angle formed on the protractor, which will be less than 180 degrees. Subtract this measurement from 360 degrees to find the reflex angle. For example, if the smaller angle measures 120 degrees, the reflex angle would be 360 - 120 = 240 degrees.
