 SSS  is when we know three sides of the triangle, and want to find the missing angles. To solve an SSS triangle: 1  use The Law of Cosines first to calculate one of the angles. 2  then use The Law of Cosines again to find another angle. 3  and finally use angles of a triangle add to 180Â° to find the last angle.
Show the angles below using two pencils. Try to âseeâ the circle that is traced out in the air. This is a 1-degree angle! an obtuse angle; 127Â°. a right angle; 90Â°. How to measure an angle with a protractor 1  : Place the midpoint of the protractor on the VERTEX of the angle. 2  Line up one side of the angle with the zero line of the protractor (where you see the number 0). 3  Read the degrees where the other side crosses the number scale.
