IN MATH: 1. n. a segment of a curve, often of a circle; the set of all points between and including two specific points of a curve. EX. Arc AB includes the points A and B and all the points lying on the circle between them.   2. a prefix meaning "the angle whose." EX. The Arcsin (.5) is /6, in common numbers 30°. To simplify the expression mentally think "the angle whose sine is .5"   Read a complete explanation at arc.htm

IN ENGLISH: 1. n. the band of light sometimes created as electricity passes between electrodes. 2. as defined above.

• Let the computer do angle and arc measure and sector area computation for you at the: Computation Page.
• Play with angle and arc measure and sector area at: arc length, linear speed, and angular speed info
• Just see the formulas and rational for arc length, linear speed, and angular speed sat: arc

APPLICATION: See list 260

1. Determine the measures of angle BAD, angle BED, and arc BE.

2. Name the minor arc determined by inscribed angle FIT.
