transformational geometry
Across
- 4. the coordinate plane is divided into four equal parts by the intersection of the x-axis (the horizontal number line) and the y-axis (the vertical number line)
- 7. a two-dimensional shape with four sides, four vertices, and four angles.
- 11. the act or process of reducing
- 14. a transformation, which is used to resize the object
- 15. a flat closed shape having 4 straight sides, with one pair of parallel sides.
- 16. the set of all output values it may produce.
- 17. the ratio between the scale of a given original object and a new object
- 19. the principal or horizontal axis of a system of coordinates, points along which have a value of zero for all other coordinates
- 20. the set of all elements of the domain that are mapped into a given subset of the codomain
- 21. two figures having the same shape
- 22. the initial point or the starting point from where we begin our calculations or measurements.
- 23. a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.
- 24. a point about which a plane figure rotates.
Down
- 1. a mirror image of the shape
- 2. a type of transformation that takes each point in a figure and slides it the same distance in the same direction.
- 3. a reference point used to appropriately scale the dilation of a figure
- 5. the ratio that defines the relation between the actual figure and its model.
- 6. a four-sided plane rectilinear figure with opposite sides parallel.
- 8. a parallelogram with opposite equal acute angles, opposite equal obtuse angles, and four equal sides
- 9. a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point.
- 10. the secondary or vertical axis of a system of coordinates, points along which have a value of zero for all other coordinates
- 12. an ordered pair of numbers a and b, written a / b where b does not equal 0.
- 13. a type of transformation where we change the size of the original shape to make it bigger or smaller by multiplying it by a scale factor.
- 18. a two-dimension surface formed by two number lines.
