Question

The first triangle is dilated to form the second triangle select true or false for each statement

A:the scale factor is 0.625 true or false?

B: The scale factor is 1.6 true or false??

Answer 1

Part(A)False Part(B) True

Explanation:

Answer 2

Part A) Is False

Part B) Is True

Explanation:

we know that

the scale factor is equal to divide the length of the corresponding side of the second triangle by the length of the corresponding side of the first triangle

Let

z-----> the scale factor

x-----> the length side of the second triangle

y------> the length side of the first triangle

so

`z=(x)/(y)`

In this problem we have

`x=0.8\ units`

`y=0.5\ units`

substitute

`z=(0.8)/(0.5)=1.6`

`1.6 > 1` ------> is an enlargement

Verify the statements

Part A) the scale factor is
`0.625`

The statement is false, because the scale factor is
`1.6`

Part B) the scale factor is
`1.6`

The statement is True -----> see the procedure
