Chapter 1: Angles and shapes

7. A figure with bases that are formed by congruent circles in parallel planes
10. A line segment where the faces of a shape interact
11. Points that lie in the same plane
12. The common endpoint of an angle
13. A solid where all the faces exept the base intersect at a point called the vertex and the base is a polygon
16. A polygon for which there is no line that contains both a side of the polygon and a point in the interior of the polygon
18. A polygon for which there is a line containing a side of the polygon that also contains a point in the interior of the polygon
19. A one-dimensional figure going infinitely in two directions
22. A unit of measure used in measuring angles and arcs
23. Two angles with measures that have a sum of 180 degrees
26. The number of square units needed to cover a surface
29. A measurable part of a line that consists of two points
30. A solid with a circular base, a vertex not contained in the same plane as the base, and a lateral surface area composed of all points the segments connecting the vertex to the edge of the base

1. In space, the set of all points that are a given distance from a given point, called the center
2. A boundless three-dimensional set of all points
3. An angle with a degree measure less than 90
4. The intersection of two noncollinear rays at a common endpoint
5. The point on a segment halfway between the endpoints

8. The sum of the areas of all faces and side surfaces of a three-dimensional figure.
9. The sum of the lengths of the sides of a polygon

25. The rays of an angle
27. Points that lie on the same line
28. The length between two points
