Using the idea that two tangent lines from a point are equal find the perimeter of a circle

Learn how to solve problems with tangent line. A tangent line to a circle is a line that touches the circle at exactly one point. The tangent line to a circle makes a right angle with the radius of the circle at the point of its tangency. Thus, to solve for any missing value involving the tangent to a circle, we apply the above relationship and create a right triangle with the tangent line and the radius of the circle as the legs. #geometry #circles
