Question

ABC ~ DEF and the scale factor from ABC to DEF is 1/2, what are the lengths of DE

Answer 1

Answer:

13

Step-by-step explanation:

ABC ~ DEF means that ABC and DEF are the same triangle either expanded or contracted.

In this case the scale factor is 1/2. That means DEF is half ABC.

Since AB = 26 then DE must be 26/2 = 13
