In your solution, two vectors are the same, if they form a line together with the origin of the coordinate system. Also normalization normally doesn't change the orientation of the vector, while for your problem rotations of pi should also be considered as equal. If both of these points apply, your solution is fine – user4668606
WebThis answer is about approximate collinearity, and can be used when the coordinates are not exact (floating-point). The angle between the line segments 12 and 23 is given by arctan y 2 − y 1 x 2 − x 1 − arctan y 3 − y 2 x 3 − x 2. To compare this angle to a small tolerance δ, we cancompare the tangents, like Web20 jun. 2024 · Revise how to work out the equation of a straight line using coordinates and the gradient, and vice versa.
