Feels very important for teachers to be more familiar then, in order to support students to understand them too.

fwiw my interpretation of the mark scheme is that this scores just 2 as the factorisation is incorrect from line 5 to line 6. If anyone feels that this would score 3 let me know!

This will hopefully give students an indication of which universities are more or less flexible on their entry criteria, to help them make their choices. Subjects are in tabs along the bottom (eg Maths, Physics, Comp Sci, etc) The data is for 2026 entry. wykecollege-my.sharepoint.com/:x:/g/person...

Very interesting. In UK exams they must use correct language for credit in exams, including ‘alternate segment theorem’, ‘angles in the same segment are equal’ and more

That’s the one

Agreed this strategy is good- wish they’d rename it to something like the chord-tangent theorem

Are you a teacher in the US? I believe you may refer to this angle rule differently. The phrasing is exactly what our students find tricky- I don’t think it’s a very good name but it’s what they need to know.

These are pairs of angles and their partner in the alternate segment

And where, might I ask, is that marvellous shirt from?
