Determining angles in a triangle

WebIf you know two angles of a triangle, it is easy to find the third one. Since the three interior angles of a triangle add up to 180 degrees you can always calculate the third angle like this: Let's suppose that you know a triangle has angles 90 and 50 and you want to know … WebAdd a comment. 1. Drop a perpendicular from x 1 y 1 to get a right triangle with the adjacent and opposite of a both equal to 50. Hence a = π / 4 (because tan a = O A = 50 50 = 1 ). EDIT: Note π / 4 radians equals 45 degrees. The result here is invariant under translation (it stays the same when the points move).
