Transformations

Front

Dilate the figure by a scale factor of 3 with the origin as the center of dilation. What are the coordinates of the image for A(3,3)?

Back

A'(9,9)

Front

Identify the transformation from ABC to A'B'C'. If the transformation is (x+8, y+4), what is the new position of point A?

Back

A' is at (x+8, y+4)

Front

What is the definition of a transformation in geometry?

Back

A transformation is a function that maps a set of points to another set of points, altering their position, size, or orientation.

Front

What is the difference between a translation and a reflection?

Back

A translation slides a figure without changing its shape or orientation, while a reflection flips a figure over a line.

Front

What is the scale factor in dilation?

Back

The scale factor is the ratio of the length of a side of the image to the length of the corresponding side of the original figure.

Front

If a figure is rotated 180 degrees, what is the rule for the coordinates (x, y)?

Back

(-x, -y)

Front

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same shape and size, but may be in different positions or orientations.
