Statement 1: If ` vec ua n d vec v` are unit vectors inclined at an angle `alphaa n d vec x` is a unit vector bisecting the angle between them, then ` vec x=( vec u+ vec v)//(2sin(alpha//2)dot` Statement 2: If `"Delta"A B C` is an isosceles triangle with `A B=A C=1,` then the vector representing the bisector of angel `A` is given by ` vec A D=( vec A B+ vec A C)//2.`
