Distance Problems (Point to Line, Point to Plane)
10 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest — every one with a full worked solution. Work through them free, no account needed.
Sample: the first question, solved
Which formula gives the distance from a point (x₁,y₁,z₁) to the plane Ax+By+Cz+D=0?
📘 Worked solution
✓The distance formula divides the absolute value of the plane expression evaluated at the point by the magnitude of the normal vector: d=|Ax₁+By₁+Cz₁+D|/√(A²+B²+C²).
And one from the hard end
Find the distance from (0,0,0) to the plane 2x+3y−z−6=0.
