# data[].attributes.body
A number that, when multiplied by the side lengths of a figure, gives the corresponding side lengths of a scale copy of the figure.

# data[].attributes.body
Any figures related by dilation with congruent corresponding angles and corresponding side lengths related by a constant scale factor.

# data[].attributes.body
A transformation that creates a scale copy using:

A center of dilation (fixed point)

A scale factor

# data[].attributes.body
Any two, or more, figures are congruent if ALL corresponding sides and angles have the same measure. Congruent figures also have the same area and perimeter and are related by one or more rigid transformations.

# data[].attributes.body
A move that creates an image from a pre-image by flipping it over a fixed line (line of reflection / linea de reflexion).

# data[].attributes.body
A move that creates an image from a pre-image by turning it clockwise / en sentido horario or counterclockwise / en sentido antihorario around a fixed point (center or point of rotation / centre de rotatcion).

# data[].attributes.body
A move that creates an image from a pre-image by sliding it up / arriba, down / abajo, left / izquierda, and/or right / derecha.

Rigid Transformation / Transformacion Rigida

# data[].attributes.subject
Rigid Transformation / Transformacion Rigida

# data[].attributes.body
Any move that creates an image without changing the angles or side lengths of the pre-image: translations (traslacions), reflections (reflejos), & rotations (rotacions) are all rigid transformations.

Corresponding Sides & Angles / Lados y Angulos Correspondientes

# data[].attributes.subject
Corresponding Sides & Angles / Lados y Angulos Correspondientes

# data[].attributes.body
Sides and angles that are in the same relative position; the sides and angles that would "match up" if you put one figure on top of the other.
