Geometry

2. the perpendicular distance from the base of a figure
4. cut in two congruent halfs
6. A shape or solid which has an indentation or "cave". Formally, a geometric figure is concave if there is at least one line segment connecting interior points which passes outside of the figure.
8. A figure that is self-similar. That is, no matter how far you zoom in on the figure, the portion you look at is similar to the original figure. The Koch edge, below, is a fractal
11. A circle that passes through all vertices of a plane figure and contains the entire figure in its interior.
12. next to or neighboring
14. a line. A description of any graph or data that can be modeled by a linear polynomial.

1. A transformation in which a graph or geometric figure is picked up and moved to another location without any change in size or orientation.
2. Two rays sharing a common endpoint. Angles are typically measured in degrees or radians.
3. a polygon with ten sides
5. Perfectly flat and level. For example, the horizon is horizontal. So is the floor.
7. an angle with less than a 90 degrees or but more than 0
9. the vertex a the tip of a cone or pyramid
10. constant not changeing, not moving
13. plurel of axis
