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 WebThe circle theorems are statements that state results about various components of circle. Some of the important circle theorems statements are: The angle subtended by a chord at the center is twice the angle …

WebExample 1. Earlier, you were given a problem about a secant line to a circle. In the circle below, m C D ^ = 100 ∘, m B C ^ = 120 ∘, and m D E ^ = 100 ∘. Find m ∠ B F E. This is an example of two secants intersecting outside the circle. The intersection angle of the two secants is equal to half the difference between their intercepted arcs. WebThe exterior angle of a cyclic quadrilateral is equal to the interior opposite angle. A radius or diameter that is perpendicular to a chord divides the chord into two equal parts and vice versa. A tangent to a circle is …
