10.3 Inscribed Angles Intercepted arc. Definition of Inscribed Angles An Inscribed angle is an angle with its vertex on the circle. Inscribed Angles By the end of today, you will know what an inscribed angle is and how to find its measure. Section 10-3 Inscribed Angles Inscribed angles An a...
If we look closely at the diagram, we can see inscribed angle CAB and its intercepted arc, which is arc BC. Since inscribed angles are half the measure of their intercepted arc, angle CAB is equal to 1/2(60 degrees), which is 30 degrees. ideo: Inscribed Angle and Arc Relationship id...

Inscribed Angle Examples Lesson Summary FAQs Activities How do you find the measure of an inscribed angle in a circle? To find the measure of an inscribed angle, in the context of this lesson, the measure of the intercepted arc must be given. Simply divide that measurement by two. How ...
Another term that must also be clear is the intercepted arc. The intercepted arc is the part of the circle between the intersection points of the sides of the angle and the circle. In the previous example, arc DT is the intercepted arc of the inscribed angle ∠DRT while arc SB is the ...
Inscribed angle theorem:This theorem states that the measure of the inscribed angle is equal to half the measure of its intercepted arc. Intercepted arc:An intercepted arc is a portion of the circumference of the circle between a tangent line and a chord. ...
