Across
2.any unbroken part of the circumference of a circle or other curved line
4.an arc of a circle having measures less than or equal to (radians)
7.the radian measure of a central angle of a circle is defined as a ratio of the length of the arc the angle subtends
8.a four-sided polygon with four angles
9.at equal distances
10.the line segment connecting two points on a circle's circumference is a chord
12.endpoints both lie on the circle
14.a segment with one endpoint on a circle, one endpoint outside the circle, and one point between these points that intersects the circle
15.the ratio of the hypotenuse to the shorter side adjacent to an acute angle in a right triangle
17.in a circle is a polygon, vertices of which are placed on a circumference
18.whose endpoints are the points of tangency and the fixed point outside the circle are equal
20.the segment of a circle is the region bounded by a chord and the arc subtended by the chord
21.a plane curve at a given point is the straight line that "just touches" the curve at the point
23.a circle which passes through all the vertices of the polygon
25.the relationship between two lines which meet at a right angle
26.an area or portion that is distinct from the others
27.the amount of 3-dimensional space an object occupies
28.the length of a line segment from its center to its perimeter
29.the segment contained by a secant segment with an endpoint on the circle and at the fixed point outside the circle whose points all lie outside the circle
30.a central angle is an angle whose apex is the center O of a circle and whose sides are radii intersecting the circle in two distinct points
31.any straight line segment that passes through the center of the circle and whose endpoints lie on the circle
Down
1.half of a sphere; also known as half of the Earth
2.the measure of the distance along the curved line making up the arc
3.an arc of a circle that measures greater than of equal to (radians)
5.2 or more arcs in congruent circle are congruent if they have the same angle measure
11.all corresponding angles are congruent; the ratios of the measures of corresponding sides are equal
13.an angle formed by two chords in a circle which have a common endpoint
16.circles that have the same radius
17.the arc that is formed when segments intersect portions of a circle and create arcs
19.the sum of all the areas of all the shapes that cover the surface of the object
22.the size of a surface; the amount of space inside the boundary of a flat 2-dimensional object
24.a line segment that bisects one of the vertex angles of a triangle
