7.1 Dilations (Finding Scale Factor)

Front

What happens to a figure when the scale factor is greater than one?

Back

The figure undergoes an enlargement.

Front

Which side length on the scaled copy corresponds to the side length HJ on the original image?

Back

AB corresponds to HJ.

Front

What is the scale factor from the small figure to the larger one if the larger figure is four times the size of the smaller one?

Back

The scale factor is 4.

Front

In the algebraic representation (x,y) to (kx,ky), what does the variable 'k' represent?

Back

The variable 'k' represents the scale factor.

Front

What do similar figures have in common?

Back

Similar figures have the same shape but different sizes.

Front

What is the effect of a scale factor less than one on a figure?

Back

The figure undergoes a reduction.

Front

If a triangle has sides of lengths 3, 4, and 5, what will be the lengths of the sides after a scale factor of 2 is applied?

Back

The new side lengths will be 6, 8, and 10.

Front

How do you calculate the scale factor between two similar figures?

Back

Divide the length of a side of the larger figure by the length of the corresponding side of the smaller figure.

Front

What is the relationship between the angles of similar figures?

Back

The corresponding angles of similar figures are equal.

Front

If a rectangle has a width of 2 and a length of 5, what will be its dimensions after a scale factor of 3 is applied?

Back

The new dimensions will be 6 (width) and 15 (length).
