Measuring Reflex and Acute Angles

The video tutorial explains how to measure reflex angles using three different methods. The first method involves drawing an extra line to measure the angle underneath and adding it to 180 degrees. The second method uses the concept that angles around a point add up to 360 degrees. The third method involves measuring the acute angle inside and subtracting it from 360 degrees. The tutorial concludes with a summary of the methods discussed.
