Transformational Geometry Review

Front

What transformation is represented by the coordinates (x, y) ----> (x + 2, y - 3)?

Back

Slide right 2, down 3.

Front

A dilation always produces a similar figure. Similar figures have the same ______ but different ______.

Back

Shape; sizes.

Front

What is the transformation shown when a figure is flipped over a line?

Back

Reflection.

Front

If a figure is in Quadrant II and is rotated 180 degrees, which quadrant will it end up in?

Back

Quadrant IV.

Front

What is the result of a dilation with a scale factor of 3 on the coordinates A(3,3), B(6,6), C(9,3)?

Back

A'(9,9) B'(18,18) C'(27,9).

Front

What is a translation in geometry?

Back

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

Front

What does it mean for two figures to be similar?

Back

They have the same shape but different sizes.

Front

What is the effect of a 90-degree clockwise rotation on a point (x, y)?

Back

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

Front

What is the center of dilation?

Back

The fixed point in a dilation from which all points are expanded or contracted.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a figure around a point, while reflection flips it over a line.
