1 All Physician Training licenses expire on August 31, 2015, are good for three years, and can only renew once (for a total of six years).  All Physician Assistant licenses expire on January 31 of even-numbered years.
Remember -- the sum of the degree measures of angles in any triangle equals 180 degrees. Below is a picture of triangle ABC, where angle A = 60 degrees, angle B = 50 degrees and angle C = 70 degrees. If we add all three angles in any triangle we get 180 degrees. So, the measure of angle A + angle B + angle C = 180 degrees. This is true for any triangle in the world of geometry. We can use this idea to find the measure of angle(s) where the degree measure is missing or not given.
A Right triangle contains a 90 degree angle. This can be any of the three angles that make up the triangle. An Acute triangle has an angle that is greater than 0 degrees and less than 90 degrees. An Obtuse triangle is an triangle that contains an angle that is greater than 90 degrees and less than 180 degrees.
