Circle exterior angle theorem
WebAlternate Exterior Angles Theorem. If a transversal intersects two parallel lines, then the alternate exterior angles are congruent. Converse also true: If a transversal intersects two lines and the alternate exterior angles are congruent, then the lines are parallel. The alternate exterior angles have the same degree measures because the lines are http://www.kutasoftware.com/freeige.html

WebJan 21, 2024 · Case #3 – Outside A Circle. And lastly, the third situation is when two secants, or a secant and a tangent, intersect outside the circle. In this case, there are three possible scenarios, as indicated in the images below. Notice that the exterior angle that is created by the intersection of two secants or tangents is one-half the difference ... WebExample 1: Using the exterior angle theorem, find the value of x from the following figure. Solution: To find: Value of x. Given: Exterior angle of triangle = 160º. Using exterior angle theorem, x + 3x = 160º. 4x = 160º. x = 160º/4 = 40º.
