[Solved] If a line is perpendicular to one of the projection planes and lies on other two planes then the line will lies on reference line accordingly.

Q.	If a line is perpendicular to one of the projection planes and lies on other two planes then the line will lies on reference line accordingly.
A.	true
B.	false
Answer» A. true
Explanation: if a line is perpendicular to one of the projection planes and lies on other two planes then the line will lies on reference line accordingly. as any line lies on two planes it will definitely passes through the reference line and so which is perpendicular to other plane.
