WebNow we will look at the Bow Theorem. The theorem states that: The inscribed angles subtended by the same arc or chord are equal. Arcs that contain equal angles are equal. … WebMar 26, 2016 · No worries: The solution technique is the same for both. Here’s how to solve it: Draw the segment connecting the centers of the two circles and draw the two radii to the points of tangency (if these segments haven’t already been drawn for you). The following figure shows this step.
WebRadians are not used for inscribed angles; their purpose is to resemble and serve as a unit of measurement for the central angle derived from the ratio of the arc length of a central angle and the radius of the circle.
