Triangles DEF and HJK are similar. DEF has side lengths DE=4, EF=6, FD=8. Which of the following could be the side lengths of HJK?• 2, 6, 7• 2, 5, 7• 8, 12, 16• 5, 7, 9

Respuesta :

Okay, here we have this:

Considering the provided information, and side lengths, we are going to idenitfy which option could be the side lengths of HJK, so we obtain the following:

So let's remember that two triangles are similar when their corresponding sides are in proportion, so let's analyze the options one by one:

We will see if the three corresponding sides are in proportion, that is, the ratios must be equal:

• 2, 6, 7:

4/2=6/6=8/7

Since corresponding sides do not have the same ratio, then this option is incorrect.

• 2, 5, 7:

4/2=6/5=8/7

Since corresponding sides do not have the same ratio, then this option is incorrect.

• 8, 12, 16:

4/8=6/12=8/16

Since corresponding sides have the same ratio, then this option is correct.

• 5, 7, 9:

4/5=6/7=8/9

Since corresponding sides do not have the same ratio, then this option is incorrect.
