SparksMaths | GeoGebra: Chord Bisectors - dynamic Circle Theorems in under 1 min #shorts #geogebra @SparksMaths | Uploaded 9 months ago | Updated 1 hour ago
Making an interactive and moving demonstration of circle theorems helps reinforce what the situation is. You can do it very quickly and easily in GeoGebra. This one is for the fact that a perpendicular bisector of a chord in a circle will always pass through the centre of the circle (and conversely, a line through the centre of a circle perpendicular to a chord will bisect it).
