Question

10 POINTS

The first triangle is dilated to form the second triangle. Select True or False for each statement. Statement True False The scale factor is 0.4. The scale factor is 2.5. A right triangle with a side length of 2. An arrow points to a larger right triangle with a side length of 5

Answer 1

Take the length of the larger divide it by the smaller

5/2 = 2.5

Answer 2

The scale factor is 0.4 - FALSE; The scale factor is 2.5 - TRUE

Explanation:

Since the arrow points from the smaller rectangle to the larger one, this means the scale factor must be greater than 1, since the figure is enlarged.

To find the factor that the figure is enlarged, divide the resulting length by the original length:

5/2 = 2.5
