### 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**.

### Does always a tangent to a circle pass through the center of the circle?

the tangent will never go through the center of a cirlce. The
tangent is, by definition, a line that only intersects the circle
at one point. If you look down a pencil along its long axis, so
that it appears to be a circle, and place your finger on top of and
perpendicular to the pencil, your finger is now tangent to the
circle you see.

### If a straight line intersects with a curve how many points do they have in common?

It depends what kind of curve you're talking about. if it's a
circle, and the line is tangent to the circle, then one. If it's a
circle, and the line is not tangent to the circle, then two. But if
it's a goofy shaped curve then it could be any number. But the most
likely answer to your question is 2.

### What is a tangent line with respect to a circle?

A tangent to a circle is a line which touches the circle once.
That is, it does not pass through the circle, which would mean
intersecting it twice. A way to form a tangent is draw any line
from the centre point of a circle to its edge. A line on the edge
perpendicular (at 90 degrees to) this line will be a tangent.

### What is a straight line that intersects a curve?

A straight line that intersects a circle or curve at two
points, but which has both end points outside the circle or curve
is called a secant. A straight line that links two
points on a circle or curve is called a chord. A straight
line which touches a circle or curve at one point is
called a tangent. A straight line that cuts a circle or
curve at one point is a straight line.
