3cm triangle,9cm triangle, 27cm triangle, If the pattern continues,and a fourth triangle is drawn,what would be the length of a side?
Answered by Ben
27x3=71
each triangle is an equillateral, all sides equal
71/3=27 would be each side length
Answered by Steve
Each side is 3 times the previous triangle's side.

The next triangle would have side 81.
