This video shows us how the radian measure of an angle is calculated. Remember that this does not change the angle, it is just another way for us to write its measure (somewhat in the same way that we can write a temperature in Celsius or Fahrenheit). This video shows us the measure of 1 radian, which will always be the same: 180 degrees/ pi, or about 57 degrees.
Calculating the Radian Measure of an Angle is a free educational video by AlRichards314.It helps students in grades HS practice the following standards HSG.C.B.5.
1. HSG.C.B.5 : Derive using similarity the fact that the length of the arc intercepted by an angle is proportional to the radius, and define the radian measure of the angle as the constant of proportionality; derive the formula for the area of a sector..
