Which line is perpendicular to a radius at the point of tangency?

A diameter

The secant line

The tangent line

If a line touches a circle at exactly one point, what is it called?

A tangent

A secant

A chord

A radius drawn to the point where a line touches the circle is perpendicular to that line. True or False?

False

True

Only for special circles

From an external point, tangents to a circle have what property?

Two

Three

One

Which of the following is NOT a property of tangents?

They touch at one point

They are perpendicular to the radius at the point of tangency

They pass through the circle's center

The length of a tangent from an external point depends on what?

The circle's diameter only

Distance from the point to the circle's center

What do you call a line segment from the center to the point of tangency?

A diameter

A radius

A chord

If a tangent touches a circle at T, which line is perpendicular to OT at T?
