Answer
D) 1
Explanation
A perpendicular line makes a angle of 90° with a line or a plane.
If a line is to be drawn from a point to a line or a plain it can only be one. In this case a line is to be drawn through a point A to a plane P. If the line is to be perpendicular, then is is only one.
From the choices, the appropriate answer is D) 1
Ответ:
The correct option is D.
Step-by-step explanation:
Given information: Point A lies outside of plane P.
Definition of Plane : A plane is a two-dimensional, flat surface that extends infinitely far.
Line perpendicular to a plane means, the line makes 90° angle with the plane.
Let as assume if a line passes through a point A and perpendicular to the plane P, then the number of possible lines are two.
It means line is perpendicular on two points of the plane,i.e., P₁ and P₂.
Since both line as perpendicular, therefore the length of line segment is same.
It is only possible, when
If a line passes through a point A and perpendicular to the plane P, then the number of possible lines is 1.
Therefore the correct option is D.
