A vector has two things: a size and a direction. Change either one and you have a different vector. Here you start with one vector A and turn on nine things one at a time — its length, its angle, a copy of it somewhere else, its opposite, and vectors that point the same way, the opposite way, or out of the flat plane entirely.
Nine reveals, each a separate button: Magnitude, Direction, Equal vector, Negative, Null vector, Parallel, Anti-parallel, Coplanar, Non-coplanar. Turn on as many as you like. RESET switches them all off.
A is drawn from the origin and stays fixed. Magnitude shows its length as |A| = 3.61. Direction draws the angle from the x-axis, 33.69°. Equal vector puts an identical copy elsewhere on the plane, and you can drag it around — same size, same direction, different place, still the same vector. Turning on Coplanar or Non-coplanar tilts the view into 3D so you can see which vectors lie flat together and which one lifts out.
A cannot be changed. Its values are fixed so the vocabulary stays the focus.
You should be able to look at two arrows and say whether they are equal, parallel, anti-parallel, or none of those.
