What will I learn?
This course provides a direct route to mastering circle basics like definitions, chords, arcs, and angles, advancing to tangents, secants, and power of a point. Learners will hone angle-chasing skills, draw helpful auxiliary lines, utilise Ptolemy’s theorem, and employ inversion, homothety, and coordinate methods to tackle tough contest problems accurately.
