Given AB = 18 , DE=6 , and AD = 5 find the perimeter of DEF

It’s a scalene triangle btw

so, if DEF is a triangle, where are A and B?

Or, which three points form the triangle, and what are the other two points?

To find the perimeter of DEF, we need to know the lengths of all three sides of the triangle DEF. From the given information, we know that side DE has a length of 6 units. However, we don't have enough information to directly determine the lengths of the other two sides.

The given lengths AB = 18 and AD = 5 seem to be irrelevant to the triangle DEF. Therefore, we need additional information, such as angles or more side lengths, to find the lengths of the remaining sides of DEF.

Please provide more information about the triangle or check if there are any missing details.
