WebA TANGENT just touches a circle (but does not cross it) The gradient of the tangent at point P is PERPENDICULAR to the gradient of the radius OP remember, perpendicular gradients multiply to -1 (they are negative reciprocals) So if P is a point on the circumference, then the gradient of the radius OP is . WebThe tangent is a straight line that touches the circle at only one point. It is perpendicular to the radius at the point of tangency. It never enters the circle's interior.

WebJan 24, 2024 · A Tangent of a Circle is a line that touches the circle’s boundary at exactly one point. The tangential point is the place where the line and the circle meet. The word “tangent” is derived from the Latin word “tangere” (which means “to touch”), which was coined by a Danish mathematician named ‘Thomas Fineko’ in the early 1800s (1583). WebA tangent is a line that just skims the surface of a circle. It hits the circle at one point only. There are two main theorems that deal with tangents. The first one is as follows: A tangent line of a circle will always be perpendicular to the radius of that circle. It will always form a right angle (90°) with the radius. city on the weser crossword
