What will I learn?

This course offers a quick and targeted way to grasp circle basics like definitions, chords, arcs, and angles, advancing to tangents, secants, and power of a point. Learners will hone skills in angle-chasing, drawing helpful lines, using Ptolemy’s theorem, and applying inversion, homothety, plus coordinates to tackle tough contest problems accurately.
