Transformation Terminology
Geometric Transformation that keeps the same size and shape
Rigid Transformation
This term describes a figure that is shrunk to half its original size during a transformation.
Reduction
Two shapes that are identical in shape and size are described as this.
Congruent
A transformation that makes a figure larger while maintaining its shape.
Enlargement
When a shape is expanded to twice its original size, this is called an ________.
Enlargement
This term indicates that two figures are the same shape but different sizes.
Similar
This word describes figures that have the same shape but not necessarily the same size.
Similar
The ratio of the length of a side of the image to the length of the corresponding side of the original figure during dilation.
Scale Factor
A triangle with angles measuring 30°, 60°, and 90° is similar to another triangle with the same angles, no matter the size. What term describes this relationship?
Similarity
Figures that can be mapped onto each other through rigid transformations are called this.
Congruent
The fixed point from which a figure is enlarged or reduced during dilation.
Center of Dilation
Two figures that can be made to coincide by rigid transformations are called this.
Congruence
