WebYou can ONLY use the Pythagorean Theorem when dealing with a right triangle. The law of cosines allows us to find angle (or side length) measurements for triangles other than right triangles. The third side in the example given would ONLY = 15 if the angle between the two sides was 90 degrees. WebUse the triangle calculator to solve the unknown angles, sides and area of a triangle by providing 3 known values. The lengths of the sides must be in the same unit. For …
