Answer» Alinethatintersects a circlein exactly onepointiscalleda tangent and thepointwhere theintersectionoccurs iscalledthepointof tangency. The tangent is always perpendicular to the radius drawn to thepointof tangency. A secant is alinethatintersects a circlein exactlytwo points.A secant is a line that intersects a circle in exactly two points. When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs. so the answer is secant |
