Chapter 9 Geometry (1st lesson)
12
dilation : a transformation whose preimage and image are similar
image : resulting figure in a transformation
isometry : a transformation in which the preimage and image are congruent
preimage : the original figure in a transformation
reflection : an isometry in which a figure and image have opposite orientations
reflectionalsymmetry : a figure has __________ if you can fold it and the edges meet
rotation : an isometry in which the figure is turned about a fixed point
transformation : a change in a geometric figure’s position, shape or size
translation : is an isometry that maps all points of a figure the same distance in the same direction
rotationalsymmetry : a figure has ________________ if it can be mapped onto itself by a rotation of 180 degrees or less
reduction : a dilation is a(n) _______________ if the scale factor is between 0 and 1
enlargement : a dilation is a(n) _______________ if the scale factor is greater than 1
