Understanding Scale Factors and Dilation

The video tutorial explains the concept of dilation, which involves changing the size of an object. It introduces the scale factor as a key determinant of whether an object undergoes enlargement or reduction. The tutorial provides examples to illustrate how different scale factors affect object size and demonstrates how to calculate new dimensions using the scale factor.

What does a dilation do to an object?

• Changes its position

• Changes its color

• Changes its size

• Changes its shape

What determines if an object gets bigger or smaller in a dilation?

• The object's position

• The scale factor

• The object's shape

• The object's color

If a scale factor is greater than one, what happens to the object?

• It becomes smaller

• It becomes larger

• It changes shape

• It changes color

What is the result of a scale factor less than one?

• Enlargement

• Reduction

• Color change

• No change

A scale factor of 0.5 results in what?

• Reduction

• No change

• Color change

• Enlargement

What does a scale factor of 2 indicate?

• Reduction

• Enlargement

• No change

• Color change

What happens to an object with a scale factor of 4/2?

• It stays the same

• It changes color

• It reduces in size

• It enlarges

A scale factor of 75/100 results in what?

• Enlargement

• Reduction

• No change

• Color change

What is the effect of a scale factor of 1?

• Enlargement

• Reduction

• No change

• Color change

If a scale factor is 1.5, what happens to the object?

• It changes color

• It stays the same

• It enlarges

• It reduces in size
