First of all one common way to estimate an angle measure is to either look at the angle and see if it matches any of the benchmarks. Or you could use a protractor to measure the angle and see what the number of degrees the angle is. Here is a video, showing how to use a protractor.
What are some common benchmark angles?
Some common benchmark angles are 90,180, 360 degrees. First of all, a benchmark angle is an angle which for example is commonly refereed to and so when you see an angle similar angled like that, you can assume its somewhere between those degrees. And the reason why 90,180, 360 degrees are common benchmark angles is because those angles are the easiest to spot and measure.
What does the measure of degrees tell you about the angle?
The measure of degrees in an angle can tell you if the angle is a right, obtuse, acute or reflex angle. For example a right angle is exactly 90 degrees. An acute is 0-90 degrees and 90-180 is obtuse. Furthermore, 180 and above is referred to as a reflex angle.
Some of the common properties of a polygon are in a polygon there has to be no spaces/openings or curves. Mainly, the shape has to be closed with no gaps, or curvy line segments,
