transformations
dialation
what is a transformation that enlarges or reduces a figure by a scale factor.
image
what is the new position of a point after a translation?
center of rotation
what is a fixed point around which shapes move in a circular motion to a new position?
rotation
what has a central point that stays fixed and everything else moves around that point?
preimage
what is the original figure?
angle of rotation
what is the degree measure of the angle through which the figure is rotated?
reflection
what is a flip across the x-axis or y-axis?
isometry (rigid motion)
what is a transformation in the plane that preserves distance and angle measure?
rotational symmetry
what is it called if you can rotate a figure 180 degrees or less so that it matches the original?
name all of the transformations
what is a dialation, reflection, translation, and rotation?
line of reflection
what is a line that a figure is flipped across to create a mirror image of the original figure?
scale factor
what is the ratio used to enlarge or reduce similar figures?
transformation
what is to slide, or move on the graph?
line of symmetry
what is a line that divides a figure into two halves that are mirror images of each other?
prime notation
what is the notation used in the labeling of points to indicate that the figure is the transformed figure?
