Across
- 3. sides, They touch the same two angle pairs. They are sides that essentially match so that they can be compared.
- 4. segment, A part of a line consisting of two endpoints, doesn't go on in either end. Also includes all the points in between the two endpoints.
- 7. Made up of two points, keeps going on both ends. Has no thickness or width.
- 11. lines, are two coplanar lines that do not intersect at any given point. They would go on forever without touching.
- 13. Also known as a slide, this action moves a figure In any direction. The size and shape of the figure remain the same.
- 15. a motion of a certain space that preserves at least one point. Commonly it is the motion of a rigid body around a fixed point, and it can be counter-clockwise or clockwise.
- 16. A figure before any given transformation or Translation. It is the figure before the new image is created.
- 17. Has a fixed starting point but no endpoint. It can go on indefinitely in one direction.
- 18. a point at the end of a line segment or ray. The point defines a line segment or ray and prevents the line from going on.
- 19. Something that cuts an object into two equal parts. It is applied to angles and line segments.
Down
- 1. moves every point of a figure or space by the same distance in a given direction. Does not change the shape or size of the figure, the figure is just moved.
- 2. the space (usually measured in degrees) between two intersecting lines or surfaces. The two intersecting lines or surfaces meet at a point called the vertex which is what creates this measure.
- 3. Figures that are exactly the same. All corresponding angles and sides are the same.
- 5. angles, are formed by the same two-line segments of the two figures. They are the angles that essentially match in the two figures.
- 6. A two-dimensional shape made by drawing a cure that is always the same distance from the center. You name this shape by its center.
- 8. lines, Lines that intersect each other. A right angle is formed when they intersect.
- 9. a point where two or more curves, lines, or edges meet. This type of point creates an angle.
- 10. a distance-preserving transformation between metric spaces. The figures remain the same through this special type of transformation
- 12. of Rotation, How many times an image maps back onto itself during a rotation of 360 degrees. It only works if the image can be rotated back to itself under a rotation of 0 to 360 degrees.
- 14. A point, line, or curve common to two or more objects. Created when two lines, planes, or figures meet or cross each other.
