Rigid Transformations

Front

What is a rigid transformation?

Back

A transformation that preserves the shape and size of a figure, including translations, rotations, and reflections.

Front

What happens to the coordinates of a point when it is translated 4 units up and 3 units right?

Back

The new coordinates are found by adding 4 to the y-coordinate and 3 to the x-coordinate.

Front

If point H(-6, 2) is translated 4 units up and 3 units right, what are the coordinates of the translated image?

Back

(-3, 6)

Front

What type of transformation is a rotation?

Back

A transformation that turns a figure around a fixed point.

Front

What type of transformation is a translation?

Back

A transformation that slides a figure from one position to another without changing its size or shape.

Front

What type of transformation is a reflection?

Back

A transformation that flips a figure over a line, creating a mirror image.

Front

What type of transformation is a dilation?

Back

A transformation that changes the size of a figure but keeps its shape the same.

Front

What does congruent mean in geometry?

Back

The same size and same shape.

Front

What is the effect of a reflection over the y-axis on the coordinates of a point?

Back

The x-coordinate changes sign, while the y-coordinate remains the same.
