Rigid Transformations Flashcard

Front

A type of transformation where a geometric figure slides horizontally, vertically, or both. Options: dilation, translation, rotation, reflection

Back

translation

Front

The original figure prior to a transformation.

Back

Pre-image

Front

A transformation that “turns” a figure about a fixed point at a given angle and a given direction.

Back

rotation

Front

Identify the transformation from ABC to A'B'C'. Options: 90^o clockwise rotation, 90^o counter clockwise rotation, Reflection across the y-axis, Reflection across the x-axis

Back

Reflection across the x-axis

Front

What is the sequence of transformations?

Back

Reflect over the y then reflect over the x

Front

Reflections over the x-axis change the sign of the ____-__________. Options: y-coordinate, x-coordinate, y-axis, x-axis

Back

y-coordinate

Front

A type of transformation where a figure is “flipped” over a line of symmetry, producing a mirror image of the figure.

Back

reflection

Front

How is trapezoid ABCD translated to trapezoid A'B'C'D'? Options: (y-8, x+5), (x+8, y-5), (x+5, y-8), (x+4, y-5)

Back

(x+5, y-8)

Front

Sequence of transformations shown: Reflect across the x-axis and then rotate -90 degrees around the origin, Rotate -90 degrees around the origin and then translate down, Reflect across the x-axis and then reflect across the y-axis, Translate up and then rotate 90 degrees about the origin.

Back

Translate up and then rotate 90 degrees about the origin.
