Generally, the equation of a circle is (x-a)2 + (y-b)2 = r2
where (a,b) is the centre of a circle, and r is the radius.
So you can use this equation along with a general line equation, y=mx+c, or using the gradient and finding the equation of the normal.

Tangent of a circle is what?
A tangent of a circle is a straight line that touches the circle at only one point.
What line meets the circle at exactly one point?
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 touching a circle at one point?
A tangent line.
What is a line that intersects a circle at only one point?
A tangent line.
The point at which a line and a circle intersect at exactly one point?
Tangent
Tangent of a circle is what?
A tangent of a circle is a straight line that touches the circle at only one point.
A line that intersects a circle at exactly one point?
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. ]
The point where the tangent line intersects a circle?
A tangent line touches the circumference of a circle at just one point but it does not intersect the circle.
What line meets the circle at exactly one point?
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 that touches the circle at one point?
A tangent is a line that touches a circle at exactly one point. It is perpendicular to the radius at the point of contact.
Which statement follows logically from the statement If a line is tangent to a circle then it intersects the circle at exactly one point?
If a line intersects a circle at exactly one point, it is a tangent to that circle
Are line may intersect a circle at exactly one point?
A tangent line touches the circumference of a circle exactly at one point.
What is the place where a tangent line intersects a circle?
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 line touching a circle at one point?
A tangent line.
Is the circle or straight line on?
A straight line touching the circumference of circle at one point is a tangent
What is a line that intersects a circle at only one point?
A tangent line.
The point at which a line and a circle intersect at exactly one point?
Tangent
