What is a dilation in geometry?

A dilation in geometry is a transformation that enlarges or reduces a figure by a certain scale factor around a fixed center point. The original shape remains parallel and proportional to the dilated shape, but its size changes. In a dilation, corresponding sides are in the same ratio, and angles remain the same.

How does a dilation affect the shape of an object?

A dilation affects the shape of an object by either enlarging or reducing it proportionally in all dimensions. The shape remains the same, but the size of the object changes. For example, if a square is dilated by a scale factor of 2, all its sides will be doubled in length, resulting in a larger square while maintaining its original shape.

What is the scale factor of a dilation?

The scale factor of a dilation is a constant by which all the distances between corresponding points in the original figure and its image are multiplied. It essentially determines how much the original figure has been enlarged or reduced in size.

How is a dilation performed?

A dilation is performed by multiplying the coordinates of each point on a figure by the scale factor to increase or decrease the size of the figure. The scale factor can be greater than 1 to enlarge the figure or between 0 and 1 to shrink the figure. The center of dilation is the fixed point from which the figure expands or contracts.

What is the relationship between the original figure and its dilated image?

A dilation is a transformation that changes the size of a figure but not its shape. The relationship between the original figure and its dilated image is that they are similar figures, meaning they have the same shape but different sizes. The dilation is a proportional enlargement or reduction of the original figure.

How can you determine the center of dilation?

To determine the center of dilation, you need to identify a point on the coordinate plane that remains fixed after the dilation has occurred. This fixed point is the center of dilation. You can do this by examining how other points have been transformed through dilation and then pinpointing the point that has not shifted or moved.

What are the possible outcomes of dilating a figure?

When dilating a figure, the possible outcomes include an enlargement or reduction of the original figure. The figure can be scaled up or down based on a given scale factor. However, the shape and orientation of the figure will remain consistent, only the size of the figure will change.

How does a dilation affect the size of a figure?

A dilation affects the size of a figure by either enlarging or shrinking it while preserving its shape. The size change is determined by the scale factor of the dilation; if the scale factor is greater than 1, the figure is enlarged, and if the scale factor is between 0 and 1, the figure is shrunk. The center of dilation serves as the point from which the figure expands or contracts. Overall, a dilation alters the size of a figure while maintaining its proportions.

What happens to the angles of a figure under dilation?

Under dilation, the angles of a figure change in size but retain their relative measures. This means that the angles will either increase or decrease in magnitude, depending on whether the figure is being enlarged or reduced, but their shape and proportionality relative to each other will remain the same.

Can a dilation result in a figure with the same measurements as the original?

No, a dilation cannot result in a figure with the same measurements as the original. A dilation involves stretching or shrinking a figure by a scale factor, which changes the size of the figure but maintains the proportions. The measurements of the dilated figure will be different from the original figure because they are scaled up or down by the factor of dilation.
