Every circle has a point called the centre. A straight line drawn through the centre and extending both ways to intersect with the circle at opposite points is called the diameter. A straight line drawn from the centre to intersect with one point of the circle is called the radius. In this case, the length of that straight line is 12 inches.

The tangent line. A secant line hits the circle in two places and forms a cord, but the tangent line only hits the circle in one point and is always perpendicular to the radius of the circle which exists at that point.

A line intersect is a point on a line where another line or object crosses the line.

tangent

No, a tangent is a line that intersects a circle at exactly one point. The radius of a circle is the distance from the center of the circle to any point on the perimeter of the circle.

A tangent line touches the circumference of a circle exactly at one point.

A tangent line touches the circumference of a circle at just one point but it does not intersect the circle.

If a line intersects a circle at exactly one point, it is a tangent to that circle

No, 2 planes may only intersect at a line, a plane, or not at all. THREE planes may intersect at a point though...

No. A tangent touches the circle at exactly one point. A line that intersects a circle at exactly two points is a secant.

Definition: a tangent is a line that intersects a circle at exactly one point, the point of intersection is the point of contact or the point of tangency. a tangent is a line that intersects a circle at exactly one point, the point of intersection is the (point of contact) or the **point of tangency**.

A tangent is a line that touches a circle at exactly one point. It is perpendicular to the radius at the point of contact.

Such a line is called a tangent line or a tangent to the circle. [Tangent is Latin for touching-- a tangent line touches the circle at just one point. ]
