What does the parallel postulate guarantee?

It states that, in two-dimensional geometry: If a line segment intersects two straight lines forming two interior angles on the same side that are less than two right angles, then the two lines, if extended indefinitely, meet on that side on which the angles sum to less than two right angles. What does the parallel

Can we equate two vectors?

For two vectors to be equal, they must have both the magnitude and the directions equal. Can we use == in vector? As long as your vector contains elements that in themselves can be compared (have operator== ), this works, yes. What does it mean when 2 vectors are equal? A vector is said to
