Transformations of Polygons

A transformation that preserves distance and angles.

• Equiangular Transfor- mation

• Equilateral Transfor- mation

• Rigid Transfor- mation

• Regular Transfor- mation

A transformation that preserves length and angle measure. 

• Equal Transfor- mation

• Equality

• Congruency

• Isometry

the resulting transformation when a transformation is applied to a figure and then another transformation is applied to the image

• corresponding parts

• center of dilation

• center of rotation

• composition of transformations

a fixed point around which shapes move in a circular motion to a new position

• center of rotation

• dilation

• image

• center of dilation

a transformation that enlarges or reduces a figure by a scale factor

• reflection

• translation

• dilation

• rotation

the line over which a figure is reflected

• line of reflection

• line of symmetry

• center of dilation

• rotation

the original figure before a transformation

• congruent

• similar

• image

• preimage

a transformation where a figure is flipped over a line and creates a mirror image of the original figure.

• reflection

• rotation

• translation

• dilation

a transformation in which a figure is turned about a fixed point

• reflection

• translation

• rotation

• dilation

if one image can be obtained from another by a sequence of transformations that includes a dilation.

• similar

• congruent

• center of dilation

• translation
