Unit 4.1 Make Up Assignment

Front

What happens when a dilation has a scale factor greater than one?

Back

The dilation is an enlargement.

Front

What does a dilation produce?

Back

A similar figure.

Front

Dilate Point B (3, -8) by a scale factor of 1/2. What is the new coordinate?

Back

(1.5, -4)

Front

How do you write the algebraic notation for a dilation with a scale factor of 3?

Back

(x, y) goes to (3x, 3y)

Front

What happens when the scale factor of a dilation is less than one?

Back

The dilation is a reduction.

Front

Define dilation in geometry.

Back

A transformation that alters the size of a figure but keeps its shape.

Front

What is the scale factor in a dilation?

Back

The ratio of the distance from the center of dilation to a point on the figure after dilation to the distance from the center to the original point.

Front

If a figure is dilated by a scale factor of 2, what happens to its area?

Back

The area is multiplied by 4 (2^2).

Front

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

Back

The figure remains unchanged.

Front

How do you determine if two figures are similar after a dilation?

Back

They must have the same shape but different sizes.
