A straight line touching the circumference of circle at one point is a tangent
A straight line is a line with the property that, if you pick any two points on the line and connect these points with a straight line, then every point on this new line lies on the original line.
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.* For moving diagrams see Related links below this box.
