The incenter is the one point in the triangle whose distances to the sides are equal. (See picture) 1  If the triangle is obtuse, such as the one on pictured below on the left, then the incenter is located in the triangle's interior.  If the triangle is acute, then the incenter is also located in the triangle's interior.
The vector forms the hypotenuse of the triangle, so to find its length we use the Pythagorean theorem. As it turns out, this formula is easily extended to vectors with any number of components. || 1  u || 2 = u 1 2 + u 2 2. 2  If a vector has more than two components, simply continue adding +u 3 2 + u 4 2 + .... Find the angle based on the cosine. You can use the arccos or cos-1 function on your calculator to find the angle Î¸ from a known cosÎ¸ value. For some results, you may be able to work out the angle based on the unit circle. 1  In our example, cosÎ¸ = â2 / 2. Enter arccos(â2 / 2) in your calculator to get the angle.
