For right triangles, you know that 1 angle is always 90°, so if you know another angle, you can use the sum of angles (180°) to figure out the third one. What is the measure of ? rt. If we know side-angle-side information, solve for the missing side using the Law of Cosines. Ads will appear on the next page refresh. In Euclidean geometry, the base angles can not be obtuse (greater than 90°) or right (equal to 90°) because their measures would sum to at least 180°, the total of all angles in any Euclidean triangle. Isosceles right triangle will have two equal sides (length x) and hypotenuse (length y). Also, the converse theorem exists, stating that if two angles of a triangle are congruent, then the sides opposite those angles are congruent. Given any angle and arm or base.
