Is there any point in learning theorem 19 if it came up in the junior cert last year ?? Thanks :)
It's probably not gonna come up, but I'd say just look over it anyway! :) I had a quick look over it - just make sure you have some idea of what's going on
Nobody knows for sure( obviously, lol) but the parallelogram theorem or Pythagoras theorem are the two that are expected.
To be safe, look over them all. Skipping over the theorem question is a huge waste of marks.
