Exterior angle of a circle
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 perpendicular to the radius drawn to the point of tangency. When two segments are drawn tangent to a circle from the same ...

WebProperty 1: In a cyclic quadrilateral, the opposite angles are supplementary i.e. they add up to 180˚. ∠a + ∠c = 180˚, ∠b + ∠d = 180˚ Property 2: The exterior angle of a cyclic quadrilateral is equal to the interior opposite angle. Example: The exterior angle ∠ADF is equal to the corresponding interior angle ∠ABC. WebAn exterior (outside) angle is an angle is considered to be outside a circle if the vertex of the angle is outside the circle and the sides are tangents or secants. There are three …
WebJan 11, 2024 · No matter the shape, a regular polygon can have its exterior angles add to no more than 360°. Think: to go around the shape, you make a complete circle: 360°. So, divide 360° by the dodecagon's twelve exterior angles. Each exterior angle is 30°. Dodecagon exterior angles. That was the easy part. The interior angles of a … 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.
