Catering to the learning needs of students in grade 5 through grade 8, these printable worksheets practice the topic pretty much across the board: easy, moderate and hard. Tangent lines to a circle This example will illustrate how to ﬁnd the tangent lines to a given circle which pass through a given point. A tangent intersects a circle in exactly one point. Because JK is tangent to circle L, m∠MJK = 90° and triangle MJK is a right triangle. Problems In the figure below, triangle ABC is tangent to the circle of center O at two points. Questions involving circle graphs are some of the hardest on the course. When two segments are drawn tangent to a circle from the same point outside the circle, the segments are congruent. Solve two challenging problems that apply properties of tangents to find the radius of a circle with a tangent. 1) L K J 190 ?
