Two Column Proofs With Circles – Geometry

This geometry video tutorial covers two column proofs with circles or you can call it circle proofs. It covers two basic examples. Theorems covered in this video are definition of perpendicular lines, right angle congruency, reflexive property, HL postulate, CPCTC, definition of segment bisectors, congruent arcs, & more.
