Across
- 2. two dimensional shape made by drawing a curve. It is always the same distance from the center.
- 5. two lines that are right angles to each other. They are straight lines coming from different directions to form right angle.
- 7. change in position, shape or size. There is a before transformation, the pre- image, and an after transformation, the image.
- 8. points that lie on the same plane. They are always 3 points and can possibly be more.
- 9. flat surface made up of points. It is normally made up of 3 or more points expressed by combination of points or one letter representing the
- 11. transformation of plane that preserves length. Examples are reflections, rotations and translations.
- 13. points that do not have to be on the same line. They are scattered throughout all different. directions consisting of more than 2 or 3.
- 15. term for when sequence of transformations take place. Example- when we reflect point B over Y- axis we get B' and then translate that 7 down its B''.
- 16. transformation which changes the size of the figure but not its shape. It is non- isometric and examples are stretch, shear and dilation.
- 17. any line which you can fold the shape in half and it maps onto itself. A example is a square or hexagon
- 18. three or more points that lie on the same graph. They all connect to one another on the same straight line expressed through points.
- 19. slides a object a fixed distance in a given direction. They pre image and image will have same shape and size just different placement on the graph.
Down
- 1. two coplanar lines that do not intersect. They can continue on forever with out touching.
- 3. transformation where pre-image and image are congruent. The size and shape stay the same but position will not.
- 4. made up of at least 2 points all connecting in a straight line. It has no thickness or width.
- 6. isometric transformation in which each point of the original figure has a figure that is the same distance from line of reflection but a different side of the line. It is the perpendicular bisector of the segment joining every point and its image.
- 10. formed by two rays and a common end
- 11. isometric transformation that turns a figure around a fixed point. An object and rotation are the same shape and size but the figure may be turned in different directions.
- 12. if the image maps onto itself under a rotation of 0 to 360 degrees. There is order of rotation (how many times the shape is rotated onto itself) divided by 360 to get your angle of rotation
- 14. A location in the graph. It has no size or shape and is expressed with a capital letter.
- 20. points that do not lie on the same plane. They can range from above 3 points.
