Dilation and Similarity in Geometry Flashcard

Front

Which transformation changes the size of a figure but keeps its shape the same?

Back

Dilation

Front

What happens to the angles of a figure after a dilation?

Back

The angles remain the same.

Front

What does the scale factor represent in a dilation?

Back

The ratio of the distance of the new figure from the center of dilation to the distance of the original figure from the center of dilation.

Front

If the scale factor of a dilation is less than 1, what happens to the image?

Back

The image becomes smaller than the original.

Front

What is the center of dilation?

Back

A fixed point from which all points on a figure are moved during dilation.

Front

Define Dilation in geometry.

Back

A transformation that alters the size of a figure while maintaining its shape.

Front

What is a scale factor greater than 1 in dilation?

Back

The image becomes larger than the original.

Front

How does dilation affect the lengths of sides in a figure?

Back

The lengths of the sides are multiplied by the scale factor.

Front

What is the relationship between similar figures and dilation?

Back

Similar figures can be obtained from one another through dilation.

Front

What is the effect of a scale factor of 1 in dilation?

Back

The image remains the same size as the original.
