wow its been a long time since freshman geometry but isnt it a law or definition that all altitudes are lines drawn from the vertex of a triangle perpendicular to the oposite side

a) since RQ is a straight line, <RQ is 180 degrees. 180 - ACB= 90 degrees.

ACR=45 degrees (goes to the centre of the square).
BCQ is also 45 degrees (also goes to the centre of the square)
ACR=BCQ=45 degrees.
From there you can deduct that QA is perpendicular to RP.

I'm sorry I can't be of more help, but I just got home from the Canadian Auto show, and I'm gonna go to sleep.

good luck!
