Finding Scale Factor Between Similar Shapes

What defines similar figures in geometry?

• Figures with the same shape but different sizes

• Figures with different shapes and sizes

• Figures with the same size but different shapes

• Figures that are completely identical

What are corresponding sides in similar figures?

• Sides that are perpendicular to each other

• Sides that are parallel to each other

• Sides that have different lengths

• Sides that are in the same position in each figure

How is the scale factor between two shapes determined?

• By dividing the length of a side in one shape by the length of the corresponding side in another shape

• By dividing the length of a side in one shape by the length of the non-corresponding side in another shape

• By adding the lengths of corresponding sides

• By multiplying the lengths of corresponding sides

If the scale factor from Shape A to Shape B is greater than 1, what does it imply about their sizes?

• Cannot determine the sizes from the scale factor

• Shape A is smaller than Shape B

• Shape A is larger than Shape B

• Shape A and Shape B are of the same size

What is the scale factor from a larger shape to a smaller shape?

• Equal to 1

• Equal to 0

• Greater than 1

• Less than 1

In the given example, what is the scale factor from rectangle A to rectangle B using the left sides?

• 1.5

• 3

• 2

• 0.5

What happens to the scale factor when the shape is rotated but the size remains the same?

• It becomes zero

• It remains the same

• It decreases

• It increases

How can the scale factor be visually identified in similar figures?

• By comparing the color of the figures

• By comparing the corresponding sides of the figures

• By comparing the area of the figures

• By comparing the perimeter of the figures

What is the scale factor from rectangle B to rectangle A if the ratio of corresponding sides is 3 over 15?

• 5

• 0.2

• 0.5

• 1

If the scale factor from rectangle B to rectangle A is one-third, what does this indicate about their relative sizes?

• Rectangle A is three times larger than rectangle B

• Rectangle B is three times larger than rectangle A

• Rectangle A is one-third the size of rectangle B

• Rectangle B is one-third the size of rectangle A
