Exploring Dilations and Scale Factors

What does the process of dilation at the eye doctor do to your pupil?

• Makes it change color

• Makes it move faster

• Makes it get larger

• Makes it disappear

What is the result of dilating an image while keeping its shape intact?

• Changes the color of the image

• Creates a similar figure

• Reduces the image clarity

• Creates a distorted figure

What must be true for two figures to be considered similar?

• They must have the same shape and proportional dimensions

• They must be on the same type of paper

• They must be exactly the same size

• They must be the same color

What happens if you dilate a figure but do not maintain its proportions?

• It becomes a similar figure

• It disappears

• It remains unchanged

• It becomes a distorted figure

What does a scale factor of two imply in the context of dilation?

• The image becomes twice its original size

• The image becomes less clear

• The image becomes half its original size

• The image becomes twice as wide but the same height

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

• Divide the original coordinates by the scale factor

• Multiply the original coordinates by the scale factor

• Subtract the scale factor from the original coordinates

• Add the scale factor to the original coordinates

What is the purpose of using a scale factor in dilation?

• To make the figure move on the plane

• To change the color of the figure

• To determine how much the figure should shrink or expand

• To determine how much the figure should rotate

What does the coordinate (2,1) represent in the context of a graph?

• A scaling factor

• A type of dilation

• A method of coloring

• A point on the graph

After dilating a triangle with a scale factor of two, what happens to its size?

• It becomes four times larger

• It becomes half

• It doubles

• It remains the same

What is necessary to maintain when dilating a figure to ensure it remains a similar figure?

• Orientation

• Proportional dimensions and shape

• Position on the graph

• Color and texture
