Question

An oak tree, elm tree, and maple tree are standing in a park. The three trees are non-collinear. If the oak is 2 feet from the elm, the elm is 10 feet from the maple and the oak is 4 feet from the maple, do these three trees form a triangle?

Answer 1

No they do not form a triangle because 2×2=4 and 4×4=16 16+4=20 it must equal 10 to form a triangle
