Unit 2 Catchup Plan

Front

What is the formula to calculate the scale factor?

Back

Scale Factor = \frac{new}{old}

Front

If the side length of AB is 10 and the new side length A'B' is 2, what is the scale factor?

Back

\frac{2}{10} = \frac{1}{5}

Front

What side is corresponding to side AB?

Back

DE

Front

What is the slope of the slope triangle if the rise is 2 and the run is 5?

Back

\frac{2}{5}

Front

If B is at 2 and B' is at 4, what is the scale factor?

Back

2

Front

If the scale factor is \frac{1}{2}, what will the image look like?

Back

It will be SMALLER than the original.

Front

Define 'corresponding sides' in similar figures.

Back

Corresponding sides are the sides in two or more figures that are in the same relative position.

Front

What does a scale factor greater than 1 indicate?

Back

The image is larger than the original.

Front

What does a scale factor less than 1 indicate?

Back

The image is smaller than the original.

Front

If the original triangle has sides of lengths 3, 4, and 5, what are the lengths of the sides if the scale factor is 2?

Back

6, 8, and 10.
