Transformations

Front

What happens to the coordinates (x,y) when you translate them 6 units up?

Back

The new coordinates will be (x, y+6).

Front

What is a reflection in geometry?

Back

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

Front

What are the coordinates of point A(3,3) after dilating by a scale factor of 3?

Back

A'(9,9).

Front

Describe the transformation represented by (x, y) -> (y, -x).

Back

This transformation is a rotation 90 degrees clockwise.

Front

What is the result of reflecting a point across the x-axis?

Back

The y-coordinate of the point changes sign, resulting in (x, -y).

Front

What is the scale factor in dilation?

Back

The scale factor is a number that describes how much a figure is enlarged or reduced.

Front

What does a rotation of 90 degrees counterclockwise do to the coordinates (x,y)?

Back

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

Front

What is the difference between translation and rotation?

Back

Translation moves a figure without changing its orientation, while rotation turns a figure around a point.

Front

If a figure is dilated by a scale factor of 1, what happens to its size?

Back

The figure remains the same size; it does not change.

Front

What is the effect of a reflection across the y-axis on the coordinates (x,y)?

Back

The x-coordinate changes sign, resulting in (-x, y).
