Circle theorems resource pack
This bumper circle theorems resource pack contains a carefully selected compilation of exam questions with fully-worked solutions designed for students to go through at home, saving valuable time in class.
There are also three carefully thought-out worksheets for students taking their first steps working with the circle theorems.
Finally, there’s a poster for circle theorems, which provides a great reference for the main theorems.
Fill in the blanks
These sheets contain sketches of circle theorems and blanks for the students to fill in in their own words.
They can then use the notes in a future lesson to fill in the blanks on the ‘Fill In The Blanks’ sheet.
The idea was to save them drawing poor sketches in their books and to write the rules in their own words.
