Rigid Transformations Practice

Front

What is a rigid transformation?

Back

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

Front

What are the rotation rules for 90° clockwise?

Back

The rotation rule for 90° clockwise is (x, y) → (y, -x).

Front

What are the coordinates of a point (x, y) after a 180° rotation?

Back

The coordinates after a 180° rotation are (-x, -y).

Front

What happens to a point when it is reflected across a line of symmetry?

Back

The point remains the same distance from the line of symmetry but is on the opposite side of the line.

Front

What are the coordinates of the point (3, -5) after a 270° clockwise rotation?

Back

The coordinates after a 270° clockwise rotation are (5, 3).

Front

What is the effect of a reflection on the coordinates of a point?

Back

A reflection changes the position of a point across a line, but the distance from the line remains the same.

Front

What is the rotation rule for 270° clockwise?

Back

The rotation rule for 270° clockwise is (x, y) → (-y, x).

Front

What does it mean for a transformation to preserve size and shape?

Back

It means that the figure does not change in dimensions or form after the transformation.

Front

What is the result of rotating the point (4, 1) 180° clockwise?

Back

The result is (-4, -1).

Front

What is the definition of symmetry in geometry?

Back

Symmetry in geometry refers to a balance or correspondence in shape and size on either side of a dividing line.
