Vectors exam question

[brazen patio]

Create a general vector and do the dot product with both AB and BC

Since it can be any perpendicular vector lets just say the perpendicular vector when z is 1

And then you'll have simultaneous equation witj just x and y and solve

Thank you!

[ornate vapor]

how do i deduce a cartesian equation for the perpendicular vector tho?

[brazen patio]

cartesian equation of the plane

ax + by + cz = d

[brazen patio]

r.n = k and you convert it to this
