Question

Smaller triangle L M N P is inside larger triangle L prime M prime N prime P. The length of L M is 4 and the length of M N is 6. The length of L prime M prime is 12.
Rectangle LMNP was dilated using the rule DP,3. Which statements are true? Check all that apply.
The length of line segment M'N' is 18 units.
The length of segment M'N' is 14 units.
The dilation is a reduction.
The dilation is an enlargement.
The scale factor is One-third.
The scale factor is 3.

Answer 1

The statement that are true about the dilation are:

A. M'N' is 18 units.

D. The dilation is an enlargement.

F. Scale factor is 3.

What is Dilation?

Given that rectangle LMNP is dilated using the rule Dp.3, it means that rectangle LMNN is enlarged times 3 to get rectangle L'M'N'P'.

This means that the scale factor is 3.

We would have the following:

M'N' = 6 × 3 = 18 units.

Therefore, the statements that are true are:

A. M'N' is 18 units.

D. The dilation is an enlargement.

F. Scale factor is 3.
