Arcs and Central Angles Section 9-3 Arcs and Central Angles Central Angle A central angle of a circle has its vertex in the center of the circle . <1 is a central angle in P 1 P Arcs An arc is an unbroken section of a circle m AB = 88˚ The measure of an arc is equal to ...
Central angles are angles whose vertices are at the center of circles. They are formed by two radii and intercept arcs on circumferences. To determine their measures, either use degrees or radians—but be careful when using larger numbers as decimal places can easily throw off your calculations!
In the circle below, there is both a major arc and a minor arc. Look at the circle and try to figure out how you would divide it into a portion that is 'major' and a portion that is 'minor'. Identify arcs minor arc major arc...

However, when considering the difference between two angles, the distance function can be better defined as what might called the minimum arc distance, i.e., the minimum of the two possible angles or arcs between the two angles. That is, the minimum angle moving clockwise or counterclockwise ...
A Y-maze apparatus composed of three enclosed arms (35 cm long × 15 cm high × 5 cm wide) oriented at 120° angles from each other was used for the Y maze test to assess short-term spatial working memory. Mice were introduced at the end of one of the arms and allowed...
