If u is a unit vector, find u · v and u · w. (assume v and w are also unit vectors.) equilateral triangle A square with three unit vectors, u, v, and w, is given. The square has two diagonal lines connecting each corner, which intersect at its center.u starts at the top left corner of the square, goes right, and ends at the top right corner. v starts at the top left corner of the square, goes down and right, and ends at the center. w starts at the top left corner of the square, goes down, and ends at the bottom left corner.
