Across
  1. 3. sides, They touch the same two angle pairs. They are sides that essentially match so that they can be compared.
  2. 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.
  3. 7. Made up of two points, keeps going on both ends. Has no thickness or width.
  4. 11. lines, are two coplanar lines that do not intersect at any given point. They would go on forever without touching.
  5. 13. Also known as a slide, this action moves a figure In any direction. The size and shape of the figure remain the same.
  6. 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.
  7. 16. A figure before any given transformation or Translation. It is the figure before the new image is created.
  8. 17. Has a fixed starting point but no endpoint. It can go on indefinitely in one direction.
  9. 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.
  10. 19. Something that cuts an object into two equal parts. It is applied to angles and line segments.
Down
  1. 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. 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. 3. Figures that are exactly the same. All corresponding angles and sides are the same.
  4. 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.
  5. 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.
  6. 8. lines, Lines that intersect each other. A right angle is formed when they intersect.
  7. 9. a point where two or more curves, lines, or edges meet. This type of point creates an angle.
  8. 10. a distance-preserving transformation between metric spaces. The figures remain the same through this special type of transformation
  9. 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.
  10. 14. A point, line, or curve common to two or more objects. Created when two lines, planes, or figures meet or cross each other.
