Question

Which side length is adjacent to angle D?
Side DE: 12
Side EF: 5
Side DF: 13

Answer 1

In triangle DEF, the sides are labeled as follows: DE, EF, and DF. To determine which side is adjacent to angle D, we need to locate angle D within the triangle.

- Side DE is opposite angle F.
- Side EF is opposite angle D.
- Side DF connects points D and F.

Therefore, the side that is adjacent to angle D is **side DF**.
