Rigid Transformations modified

Front

What is a rigid transformation?

Back

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

Front

What is a nonrigid transformation?

Back

A transformation that does not preserve size and shape, such as stretching or compressing.

Front

How do you perform a 90-degree counterclockwise rotation on a point (x, y)?

Back

The new coordinates will be (-y, x).

Front

What is the effect of reflecting a point over the x-axis?

Back

The new coordinates will be (x, -y).

Front

What is the effect of reflecting a point over the y-axis?

Back

The new coordinates will be (-x, y).

Front

What is the result of rotating a point (x, y) 180 degrees around the origin?

Back

The new coordinates will be (-x, -y).

Front

How do you translate a point (x, y) right by 3 and down by 2?

Back

The new coordinates will be (x + 3, y - 2).

Front

What is the composition of transformations?

Back

The application of two or more transformations in sequence.

Front

What is the result of reflecting a triangle over the x-axis followed by a 90-degree rotation?

Back

The triangle's orientation and position will change, but its size and shape will remain the same.

Front

If triangle ABC is translated left 2 and up 3, what are the new coordinates of point A (x, y)?

Back

The new coordinates will be (x - 2, y + 3).
