Across
- 4. An undefined term in geometry, it names a location and has no size
- 8. Two angles in the same plane with a common vertex and a common side
- 9. The length of an altitude of the figure (this is what you call how tall a person is)
- 12. A pair of adjacent angles whose noncommon sides are opposite rays
- 13. The distance around the circle
- 16. A transformation that shifts or slides every point of a figure or graph the same distance in the same direction (if someone says something in German, you need this to understand it)
- 18. The point that divides a segment into two congruent segments
- 19. The sum of the side lengths of a closed plane figure
Down
- 1. The side opposite the right angle in a right triangle
- 2. Flat surface that has no thickness and extends forever (you also ride it when traveling far distances)
- 3. The original figure in a transformation
- 5. A change in the position, size, or shape of a figure or graph
- 6. Absolute value of the difference of the coordinates of the points
- 7. A trasformation across a line, called the line of ______, such that the line of ______ is the perpendicular bisector of each segment joining each point and its image (you see it when you look in a mirror)
- 8. The number of nonoverlapping unit squares of a given size that will exactly cover the interior of a plane figure
- 10. Common endpoint of the sides of the angle
- 11. A segment that has endpoints on the circle and that passes through the center of the circle
- 14. A segment whose endpoints are the center of a circle and a point on the circle; the distance from the center of the circle to any point on the circle
- 15. A figure formed by two rays with a common endpoint
- 17. A straight path that extends forever and has no thickness (you stand in it at Six Flags)
