What is the difference between a tangent line and a secant line?

• A secant intersects the circle twice; a tangent touches the circle once

• A tangent intersects the circle twice; a secant touches the circle once

• A secant goes through the center of the circle; a tangent does not

• A secant is outside the circle; a tangent is inside the circle

• Line PR

• Minor Arc

• Point V

• Secant Line

• Major Arc

• Point of Tangency

• Semi-Circle
