Dilations and Scale Factor

How do you calculate the coordinates of a point after dilation?

• Add the scale factor to the coordinates of the original point.

• Subtract the scale factor from the coordinates of the original point.

• Multiply the coordinates of the original point by the scale factor.

• Divide the coordinates of the original point by the scale factor.

What is the relationship between similar figures and dilations?

• Dilations create similar figures, which have the same shape but different sizes.

• Similar figures are always the same size and shape.

• Dilations have no effect on the similarity of figures.

• Only certain types of dilations can create similar figures.

If a dilation has a scale factor of 3, what happens to the original figure?

• The original figure is enlarged by a factor of 3.

• The original figure remains the same size.

• The original figure is reduced by a factor of 3.

• The original figure is flipped upside down.

What does the scale factor indicate in a dilation?

• It indicates the color change of the figure after dilation.

• It indicates how much larger or smaller the figure will be after the dilation.

• It indicates the angle of rotation of the figure after dilation.

• It indicates the position of the figure after dilation.

True or False: A dilation produces a congruent figure.

• True; a dilation produces a congruent figure.

• False; a dilation produces a similar figure, not necessarily congruent.

• True; a dilation changes the size but keeps the shape the same.

• False; a dilation produces a different figure altogether.

What happens to the dimensions of a figure when a scale factor of 1/3 is applied?

• The dimensions of the figure are doubled.

• The dimensions of the figure remain the same.

• The dimensions of the figure are reduced to one-third of their original size.

• The dimensions of the figure are increased by one-third.

If the scale factor is less than 1, what type of transformation occurs?

• A reduction occurs.

• An enlargement occurs.

• A reflection occurs.

• A rotation occurs.

What is the effect of a negative scale factor in a dilation?

• A negative scale factor reflects the figure across the center of dilation and changes its size.

• A negative scale factor only changes the size of the figure without reflection.

• A negative scale factor has no effect on the figure's size or position.

• A negative scale factor rotates the figure around the center of dilation.

How does the center of dilation affect the image?

• It determines the color of the image.

• It is the fixed point from which the figure is enlarged or reduced.

• It changes the shape of the image entirely.

• It affects the rotation of the image.
