Secant and Tangent Segments Circles

In a circle, if a diameter bisects a chord (that is not a diameter), then:

• it is a secant

• it is parallel to the chord

• it is perpendicular to the chord

• it is just shaking out the sillies

A tangent line intersecting with a radius always creates a ____________ angle

• right

• acute

• obtuse

• straight

A(n) _____ to a circle is a line, ray or segment in the plane of the circle that intersects the circle in exactly one point.
