Cee’s Black & White Photo Challenge: Geometry!

Geometric? I was okay at geometry, but when it morphed into trigonometry, I got lost. I had no idea what it was about. What were those numbers for?

Until I read a few books about sailing. I discovered it was a way of calculating the distance on water, taking into consideration the curve of the earth (take THAT you flat-earth people).

Triangular? Sort of?

      1. I remember it had to do with something with the 90°angle. For example if there was a wall and it threw a shadow you could work out all the angles from the wall to where the shadow hit the ground and lengths of the triangular shape that was created. Although not a very good explanation, but something in that direction I think.


  1. Geometry is the only class I ever fell asleep in. I don’t mean just blanked out, lost in a daydream kind of thing… but actually fell asleep in. Despite keeping a strange sleep schedule during my high school years that left me like a zombie, I managed to stay awake during classes… but apparently geometry did me in.
