WebA vector A is called an equal vector to vector B if they have the same magnitude and are pointed in the same direction. We can also say that two or more vectors are equal if they are co-directed (directed in the same direction), collinear (lie on the same line), and have the same magnitude (having the same length). This implies that equal vectors are also … WebApr 15, 2024 · 0. You can check the followings: 1) Find their slope if you have their coordinates. The slope for a vector v → is λ = y v x v. If the slope of a → and b → are equal, then they are parallel. 2) Find the if a → = k b → where k ∈ R. If there is a value that satisfies the above equation, then they are parallel.
