Question
The intercepts made by a plane, P , on the coordinate axes are a, b, c. The coordinate axes are rotated about the origin by an angle q. The plane P now makes the intercepts a¢ , b¢ , c¢ on the (new) coordinate axes. Which of the following statements is true?


2 + 1 b ' 2 + 1 c ' 2 '/>

The correct answer is:
Observe that the distance from the origin to the plane is invariant, since the origin and the plane are fixed.
