1. The problem statement, all variables and given/known data In rest, a triangle has sides 1, 1 and sqrt(2). Find the angles of the triangle. when it moves with speed c/2. 3. The attempt at a solution I have found u_y and u_x - it's sin(45)*c/2 and cos(45)*c/2 - so I get the angles to be 45, 45 and 90 like before - but that can't be true?
