Answer:

Let A be the point and L be the line. Suppose that B and C are two different points on line L with AB and AC both perpendicular to L. Then triangle ABC has right angles at B and C, plus an angle at A which add up to more than 180°. That does not work for a triangle in the plane whose angles have to add up to exactly 180°.
