Hello, my name is Walter Unglaub, and this is how to find the perimeter of an angle with three variables. Well this question isn't quite correct in the sense that angles do not have perimeters. An angle is a measure of the distance between two vectors in a two dimensional plane and if I'm given three variables such as the length between this point and this point, let's call it A and likewise the length between this point and this point, let's call it B, a third variable could be the distance between these two points and we can call that C. So as soon as these two points are connected through this length C, we have a triangle where theta remains unchanged and the perimeter of this triangle formed by these variables and this given angle theta is simply the perimeter. So the perimeter then would simply be A plus B plus C where this angle is known and information about the other variables could be found given other constraints, other pieces of information. My name is Walter Unglaub and this is how to find the perimeter of an angle with three variables.
