Q.	A line can’t be perpendicular to two perpendicular planes at the same time.
A.	true
B.	false
Answer» A. true
Explanation: plane is collection of infinite lines the lines present in it will parallel to all the other lines in it. perpendicular plane is such that the lines present in it will perpendicular to all the lines present in perpendicular plane. so a line perpendicular to one plane will can’t be perpendicular to perpendicular plane.
