- 1What is the a radius?Half of the diameter of a circle
- 2What is a diameter?The full length across the middle of a circle
- 3How do you find circumference?Two times pi times the radius (2nr)
- 4What is the measure of the angle if given the arc?If central angle, they are the same. If inscribed angle, the arc divided by 2
- 5How do you find the measure of a pair of adjacent angles when given the arcs on both sides?Average the two arcs
- 6What is an inscribed angleAn angle where the vertex is on the side of the circle instead of the middle
- 7What is a central angleAn angle who's vertex is in the middle of the circle
- 8What are tangent anglesangles who's vertex lies outside of the circle, and the lines cross at one point on the sides of the circle
- 9How many degrees are in half of a circle (Semicircle)180
- 10How many degrees are in an entire circle360
- 11To find the measure of a tangent angle you...Subtract the smaller arc from the larger arc and divide by 2
- 12What is a major arcAn arc that is greater than 180
- 13What is a minor arcAn arc that measures less than 180
- 14What are concentric circlesCircles that lie in the same plane, and share the same midpoint
- 15What is a semicircleHalf of a circle
- 16What is circumferenceDistance all of the way around the circle
- 17What is a chordA line whos endpoints are on the edge of a circle
- 18How do you find the diameter of a circleMultiply the radius by 2
- 19What is a circleWhen all points are the same length apart from the center
