WebCircle Properties and Circle Theorems 1. Perpendicular Bisector of Chord The perpendicular bisector of any chord of a circle passes through the centre of the circle. In … WebThese 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.
