Homework Equations


reflection matrix = 2*projection matrix - Identity matrix

The Attempt at a Solution


Using the above equation, I get that B is the projection matrix and E is the reflection matrix.
Can someone please verify if this is indeed the correct procedure?

Your justification for the projection matrix might need some fleshing out.
The equation for the reflection matrix justifies your choice of E if you can show that B is a projection matrix.
