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

What is the formula to use when solving for an intercepted arc of an inscribed angle?

• Equal to the Inscribed Angle

If an inscribed angle intercepts a diameter, then it is a(n) _ angle.

• Obtuse

• Right

• Acute
