I searched Google images but that wasn't helpful... What is the shapes of 'bent' handrail and 'angled' handrail? what's the defference?
A curvature from the beginning till the end.
A corner in an exact point between the beginning and the end.
So what you are looking for if there are certain points in each step between you may say it is angled but if it's curved as a whole and has no such points you may say bent.
An example in graphics; (sorry for my paint skills)
For bent closest shape is circular while for angled closest shape is a triangle or rectangle. You can notice angle in the names easily..
