This document contains math exercises involving vectors: 1. Find the coordinates and magnitudes of 5 vectors given their initial and terminal points. 2. Determine if 3 sets of vectors are parallel or perpendicular. 3. Find the coordinates of the vectors formed by the sides of a triangle with vertices at (11,11), (33,33), and (66,00). 4. Find the initial point of a vector if its terminal point is given as (55,22). 5. Calculate the length of the diagonals and area of a rhombus defined by its vertex points.
