Understanding Scale Factor and Similar Shapes

The video tutorial explains how to draw a similar shape using a scale factor of three. It begins by introducing the concept of scaling and labeling the sides of the original shape. The tutorial then guides viewers through the process of drawing the scaled shape by multiplying the lengths of the original sides by the scale factor. The video concludes by connecting the endpoints to complete the scaled shape and summarizing the process.

What is the scale factor used to draw the similar shape?

• Five

• Two

• Three

• Four

If a side of the original shape is 3 units, what will be its length in the scaled shape?

• 12 units

• 9 units

• 6 units

• 15 units

What is the first step in drawing the scaled shape?

• Draw a diagonal line

• Draw a vertical line

• Draw a curved line

• Draw a horizontal line

How many units do you move right to find the next endpoint in the scaled shape?

• 12 units

• 9 units

• 6 units

• 3 units

What is the length of the vertical segment in the scaled shape?

• 6 units

• 9 units

• 12 units

• 15 units

How do you determine the endpoint of a diagonal side in the scaled shape?

• Move right and up by the original units

• Move right and up by twice the original units

• Move right and up by four times the original units

• Move right and up by three times the original units

What is the final step in completing the scaled shape?

• Erase the original shape

• Color the shape

• Connect the last two endpoints

• Draw a new shape

What is the relationship between the original and the new shape?

• They are congruent

• They are different

• They are similar

• They are identical

What is the purpose of using a scale factor in drawing shapes?

• To change the shape's material

• To rotate the shape

• To make the shape larger or smaller

• To change the shape's color
