  1. Question 10: I think you should specify that said triangle is on a flat plane, since it’s possible to have more than one right angle on different planar geometries.

  2. Oh, I didn’t realise the questions change on each reload – my previous comment was in regards to the maximum number of right angles that a triangle can have.

  3. Yup, on a sphere you can have three right angles – on the Earth, Singapore, Kinshasa and the South Pole makes a triangle with three almost-right angles!

  4. Great quiz!??
