Question

A line and a plane are perpendicular if they intersect and if every line lying in the plane and passing through the point of intersection is perpendicular to the given line.

Could someone rewrite this differently?
Thx

Answer 1

A line and a plane are perpendicular if they intersect and if TWO lineS lying in the plane and passing through the point of intersection ARE perpendicular to the given line.

Answer 2

How about:
A line and a plane are perpendicular if the line is a normal to the plane.
