A real-life version of this problem presented itself today.

I installed this wall today so we could place a gate across the kitchen to keep our child safe.
I want three evenly spaced screws along the bottom of this wall.
Where should I drill the holes?
Of course, I measured, divided into three and started marking out the spots to drill. As I marked the second spot I realised my mistake… and questioned my career choice.
Here are a series of images to use this as a problem in class.
Did I get it right…?
All these image files and a PowerPoint containing these images in the zip file below.

Love your comment about your questioning your career choice. Even the “experts” make mistakes translating our theory to practise. I guess it makes a good case for more hands on learning.
Smooth job with the carpentry work!
