The unit circle defines how to find the sides and angles of aright trianglethat is formed when extending a line with a known central angle within the circle. Because the unit circle has a radius equal to 1, the triangle’shypotenuseis also always equal to 1. ...
Angles and Intercepted Arcs Circles Conic Sections: Circles More Geometry Lessons Share this page to Google Classroom In these lessons, we review and summarise the properties of angles that can be formed in a circle and their theorems. Inscribed angles subtended by the same arc are equal. ...
A central angle is an angle with its vertex at the center of the circle and its sides are the radii of the circle. What is the relationship between central angles and their arcs? The measure of a central angle is equal to the measure of its intercepted arc. ...

Arcs and Subtended Angles Segment of a Circle What is pi? Area of Sector Calculator Area of a Sector Examples Example 1:If the angle of a sector of a circle is 60°, and the radius of the circle is 7 inches, what is the area of the sector of this circle?
(2) Inscribed angles that intercept congruent arcs are congruent. Show Step-by-step Solutions Inscribed Angles and Quadrilaterals and Arcs What is the relationship between an inscribed angle and its intercepted arc? The angle is half the arc (or the arc is twice the angle). Also, if a quad...
If two chords in a circle are congruent, then their intercepted arcs are congruent. If two chords in a circle are congruent, then they determine two central angles that are congruent. The following diagrams give a summary of some Chord Theorems: Perpendicular Bisector and Congruent Chords. Scroll...
