Parsecs? nanometers? 73? I don't know how you can answer this question.

Do you mean "even" as in 2,4,6, or as a whole number ... or as in equal?
If the latter,

is a completely subjective question. This, I presume, was meant to be a practical problem...yet requires a response that measures, in some sense, not the sides of the triangle but rather how obsessively perfectionist (or blithely not) the responder is.( And, furthermore, might well be dependent on the size of the house, as well.)
On the other hand, if you're looking for a unit of measure that will ensure that the measurement of the side lengths are all reported as integers, the question reduces again to how precise you want to be (or how tolerant of deviation you're willing to be).
Regardless, I don't have much tolerance for such malformed questions.

For the triangle ABC whose sides are segments AB, BC, CA there are three vertices A, B, and C. Each one is located on two sides, e.g. vertex A is located on side AB and side AC. Similarly for vertices B and C.
Good luck, Joyce!
