Students will discover the relationship between the angle formed by a secant and tangent and the angle of the arcs of a circle. Students will investigate properties of the tangents they have drawn, including the following: 1. Relationship between tangent and radius of the circle. 2. Angle of a tangent and arc angles. Congruent tangents
