MonoMonday Challenge : Angles

I can't help stairing at all the angles in this picture. The maximum angle for domestic staircases is apparently 42° as opposed to 38° for factories and offices, and 33° for public spaces. Who knew? Teddy has adopted a jaunty angle as he looks down at me (lying almost horizontal as I angle the camera up at the stairs). The window beyond has a multitude of right angles, as well as a semi-circle bisected at 90°.


I'm angling for a win in this most excellent challenge set by JDO (thank you!) and you can see all the other entrants here.
