Cool picture, and it would have been awesome in the speed challenge. Not so sure it fits here though. I see a few right angles, but I honestly have to search for them. Really is a sweet action shot though.
I can see a right angle in the leg..arm..helmit to arm..the lower back to the seat and the front suspension to the front wheel. I think the bike is more than 90 degrees. A good action shot.(7)
A right angle with the road here would be the bike upright. I'm trying to look for other right angle references - and the only one I can think of is that this is the 'right angle' for taking the corner at a half decent speed! Focus is a bit soft on the bike.
