A tangent line must be perpendicular to a radius

• True

• False

A line that intersects a circle in exactly 1 point

• chord

• tangent

• secant

• diameter

A segment whose endpoints are on the circle

• chord

• diameter

• radius

• secant

If a tangent and a chord intersect, then each angle formed is 1/2 of its intercepted arc

• True

• False
