Proving Circle Theorems - Angle in a Semicircle WORKSHEET DESCRIPTION
Once students can identify and apply the circle theorem ‘angle in a semicircle’, it's time for them to get to grips with the proof! This worksheet will scaffold a method to prove the circle theorem. Learners can follow a step-by-step method, filling in gaps of algebraic angle labels to complete the proof.
Learners could then be asked to recreate the proof by hiding this worksheet, only referring to it if needed.
Here at Cazoom we have created similar worksheets for various circle theorems so your students can learn and recreate the proofs for all.
