1a. the set of points in a plane that are equidistant from a given point is called a a. square b. sphere c. segment d. circle 1b. the given point is called the a. vertex b. center c. axis d. radius 2. the equation x^2+y^2-4x+2y=b describes a circle. part a. determine the y-coordinate of the center of the circle. part b. the radius of the circle is 7 units. what is the value of b in the equation? 3. point q lies on st, where point s is located at (-2, -6) and point t is located at (5, 8). if sq: qt = 5: 2, where is point q on st? give the coordinates for q. (use image #1) 4. the circle with center f is divided into sectors. in circle f, eb is a diameter. the radius of circle f is 3 units. match each arc length to its subtended central angle. (use image #2 & #3)

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry. how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
