Angular; having angles
This challenge has nothing to do with Angela Merkel, German Chancellor nor is it anything to do with the joint between leg and foot, Germanic people from central Europe who inhabited England in the 5th century, or fishing.
It’s more to do with a figure formed by 2 planes diverging from a common point.
You have to twist your head at an angle to see clearly lines of steps surfaces and markings converging from/to a common point (focal) on part of the esplanade at Cadiz, Espana – only slightly hypnotic.

I agree. Love the angle of the shot, as well as the leading lines of the steps. Great choice Tony.
Excellent, your photo is a perfect example of converging lines drawing the in eye into an image!
