Is it possible to construct a quadrilateral with exactly 3 (not 4) equal sides and exactly 3 equal angles?
If so, give an example.
If not, why not?
If so, give an example.

I made a starter pack for KS5 maths (teachers, posters, and other people involved in it)
Most of the starter packs I've seen for maths teachers have been for all age groups, so this one is aimed towards sixth form (16-19 ish)
Please let me know if you'd like adding (or removing)!

Big change from Oxford University!
For 2027 entry onwards they will use the TMUA (October sitting) for maths and not the MAT.

I marked some homework on chi squared tests today. It really frustrates me that students have to do these sorts of tests by hand when of course in reality they are all done by computer.

In #mathstoday, I motivated z-scores by asking who was faster - Michael Phelps or Usain Bolt?
In past years, I had done this after introducing z-scores, but starting with the question prompted great discussion:
"You can't compare them. They're different sports."
