00:00: In this movie, we'll discuss the Angle Addition Postulate. For the diagram shown, if P is in the interior of angle RST then we can conclude that the measure of angle RSP plus the measure of angle PST is equal to the larger angle RST. Let's find the measure of the unknown angle in the diagram shown. We can see that the measure of angle EBS is 43 degrees and the measure of angle GBS is 39 degrees. To get the measure of the larger angle, we will add the two angles together to get 82 degrees. And that's the application of the Angle Addition Postulate.
