How to Find Angles in a Circle Lesson Summary Frequently Asked Questions How can the angle of an arc be found? The angle measure of an arc is the same as the measure of the two line segments that intersect to define it. That angle is opposite the arc it creates on that circle's ci...
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 point outside the circle, the segments are equal in length. The following figures show the Inscribed Angle Theorems and Angles in Circle Theorem...

Angles are formed when two rays intersect at a point. The 'opening' between these two rays is called an 'angle' which is represented by the symbol ∠. Angles are usually measured in degrees and are expressed as 60°, 90°, and so on. ...
44 related questions found What are angles made of? In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles ...
An inscribed polygon is a polygon with all its vertices on the circle. The circle is then called a circumscribed circle. If a right triangle is inscribed in a circle, then the hypotenuse is a diameter of the circle. Conversely, if one side of an inscribed triangle is a diameter, then th...
In a complete circle, there are 2π radians. 360 = 2π; radian Therefore, 1 radian = 180°/π Gradian of an Angle This unit is least used in Maths. It is also called a gon or a grade. An angle is equal to 1 gradian if the rotation from the initial to terminal side is 1/40...
Opposite Angles in a Cyclic QuadrilateralA cyclic quadrilateral is a quadrilateral whose vertices lie on a circle and it is also known as a quadrilateral inscribed in a circle. In other words, it is a quadrilateral that is inside a circle and all its vertices touch the circle. There are ...
