Scale Factor #2

The ratio of corresponding sides in a figure.

• Scale Factor

• Corresponding Angle

• Dilation

• Transformation

Sides that are in the same position from a pre-image to its image.

• Corresponding Sides

• Corresponding Angles

• The Same

• Congruent Sides

Which side length corresponds with EF?

• LM
• OL
• EH

Which angle corresponds with angle H?

• F
• L
• E
• O

What is the scale factor from the small shape to the big shape?

• 7/3
• 2
• 10/3

Are the following similar? Why or why not?

• Yes, because corresponding sides are the same

• No, the numbers are not the same

• No, the sides are 2 times larger, but the width is the same.

• Yes, because the scale factor is 2

When you use a percent that is less than 100% (like 80% or 50%) to change the original, what is true about the new image?

• The new image is larger than the original and the angles increased.

• The new image is smaller than the original but the angle stay the same.

• The new image is the same size as the original.

• The new image is smaller and so are the angles.

To shrink a pre-image, the scale factor must be...

• greater than 1

• a fraction

• less than 1

• 1

What is the scale factor from the smaller quadrilateral to the larger?

• scale factor = 4
• scale factor = 10
• scale factor = 3
• scale factor = 2
