Explore the Parallelogram Law to determine the sum or the difference of two vectors.[br][br]Move the (shared) tail and the heads of both vectors to explore different configurations.[br][br]
Two vectors are [i][color=#980000]equipollent [/color][/i](or [i]equivalent[/i]) when they have the same magnitude and the same direction, regardless of their initial point.
Is it possible to apply the Parallelogram Law when the given vectors are collinear?[br]Explore these special cases using the app, then explain your conclusions.[br][br]([i]Note[/i]: Two vectors are collinear when they have the same direction, that is, they geometrically belong to the same line.)
