# A Levels H2 math - 2008 DHS Prelim Paper 2/Q5 (Vectors - multiple planes)

This question is taken from 2008 Dunman High School Prelim paper 2 question 5.

You'll need to understand that **if three planes do not have a common point, then the line of intersection of two planes must be parallel to the third plane** to answer part (iii) of this question.

For best results, pause the video in the beginning and attempt the question by yourself before viewing the solution.
