What is a scale factor?

Back

A scale factor is a number that scales, or multiplies, a quantity. It is used to determine how much larger or smaller a figure is compared to another figure.

Front

If a triangle is enlarged by a scale factor of 2, what happens to its dimensions?

Back

All dimensions (length, width, height) of the triangle are multiplied by 2, making the triangle twice as large.

Front

What is the scale factor if a shape is reduced to half its size?

Back

The scale factor is 1/2.

Front

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

Back

Divide the length of a side of the new figure by the length of the corresponding side of the original figure.

Front

If the scale factor from triangle ABC to triangle DEF is 3/2, what does this mean?

Back

Triangle DEF is 1.5 times larger than triangle ABC.

Front

What is the scale factor if the original figure has a length of 4 cm and the new figure has a length of 8 cm?

Back

The scale factor is 2.

Front

If a map has a scale of 1 cm = 10 km, how far apart are two cities that are 4 cm apart on the map?

Back

The actual distance is 40 km.

Front

What does it mean if two lines correspond in similar figures?

Back

Corresponding lines are the lines that are in the same relative position in two similar figures.

Front

If line AB corresponds with line XY, what can we say about their lengths if the scale factor is 2?

Back

Line XY is twice the length of line AB.

Front

What is the scale factor from figure A to figure B if figure B is 1/3 the size of figure A?

Back

The scale factor is 1/3.
