4. each of the pairs of opposite angles made by two intersecting lines
8. it has four equal sides and four equal angles.

17. A line that divides a shape into two congruent parts that are mirror images of each other.
19. the distance around the outside of a circle,

1. those lines that are equidistant from each other and never meet, no matter how much they may be extended in either direction.
2. a closed curved line around a central point
5. a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance.
6. the distance from the center of the circle to any point on it's circumference.
7. the figure formed by two rays
11. a polygon with three edges and three vertices.
14. a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point.

16. a mirror image of the shape
18. an infinitely long object with no width, depth, or curvature.
20. a straight line segment whose endpoints both lie on a circular arc.
