Section 6.2 More Angle Measures in a Circle

Section 6.2 More Angle Measures in a Circle. Tangent is a line that intersects a circle at exactly one point; the point of intersection is the point of contact , or point of tangency. Secant is a line (or segment or ray) that intersects a circle at exactly two points.
