Question

Through a point, not a given line, how many perpendicular lines can be drawn to the given line?

A. Two
B. Infinite
C. None
D. Only one

Answer 1

D. Only one

Explanation:

Lines are perpendicular if they intersect to form a right angle (90°).

The perpendicular postulate tells you that when you have a line and a point not on the line, then there is only one perpendicular line that can be drawn through the point to the line.
