Angles in the Same Segment – Proof

This Angles in the Same Segment – Proof video also includes:

If angles intercept the same arc, the angles must be the same size. The quick video talks through the proof of showing the reason two inscribed angles that intersect the same arc have the same measurement. Pupils then create their own proofs with the included worksheets.
