Understanding Scaled Copies

The video tutorial explains the concept of scaled copies, using a Desmos activity as an example. It differentiates between true scaled copies and distorted images, emphasizing that scaled copies maintain the same shape but differ in size. The tutorial guides viewers on identifying scaled copies among various drawings by examining multiplicative relationships, where all sides are multiplied by the same factor. This ensures that the shape remains consistent without distortion.

What is a key characteristic of scaled copies?

• They are distorted versions of the original.

• They are always larger than the original.

• They have the same shape but different sizes.

• They are the same size as the original.

How do distorted images differ from scaled copies?

• Distorted images are exact replicas of the original.

• Distorted images are always smaller than the original.

• Distorted images have the same shape but are not proportional.

• Distorted images are the same size as the original.

In the example with the letter F, which drawings were identified as scaled copies?

• Drawings 1, 2, and 5

• Drawings 1, 2, and 7

• Drawings 2, 3, and 7

• Drawings 3, 4, and 5

What is the multiplicative factor for drawing number 2 compared to the original?

• 4 times

• 1.5 times

• 3 times

• 2 times

Which drawing has a multiplicative factor of 3 compared to the original?

• Drawing 5

• Drawing 2

• Drawing 7

• Drawing 1

What is the multiplicative factor for drawing number 1?

• 2.5 times

• 2 times

• 3 times

• 1.5 times

Why is drawing number 5 not considered a scaled copy?

• It is an exact replica.

• It is larger than the original.

• It is distorted.

• It is too small.

What ensures that a shape is a scaled copy?

• All sides are the same length as the original.

• All sides are multiplied by the same factor.

• The shape is smaller than the original.

• The shape is distorted.

What is not a characteristic of scaled copies?

• They have a multiplicative relationship.

• They have the same shape as the original.

• They are distorted.

• They are proportional to the original.

What is the main takeaway about scaled copies?

• They maintain the same shape and have proportional sides.

• They can be distorted.

• They are exact replicas of the original.

• They are always larger than the original.
