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.
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
What is a line segment that goes from one point on the circle through the center to anther point on the circle?
It is the diameter
