An unequal triangle is a closed plane figure bounded by three straight lines such that the length of at least one of the lines is different from that of another.
IF (and only if) the lines are al coplanar, then a polygon.
Three
A polygon is a shape made of three or more straight lines that surround a closed space. If you had three lines that did not make a triangle but instead looked like the letter "N," that would not be a polygon because the lines don't close a space. A space is closed when it is entirely surrounded by lines.Hope that helped :D
trisect the bottom side, and draw two lines from the top vertex to the bottom.
A polygon is a closed three or more sided figure. It can not have any curves or intersecting lines.

It is so by definition.
The lines don't need to be straight. Make them circles or curves!
it can, or it can have three a polygon is a closed figure with at least three angles and three sides and no curves.

An equilateral triangle has exactly three lines of symmetry. It is the only shape that contains exactly three lines of symmetry.
yes it does. a polygon has to be a closed figure with a least three sides and it can only have straight sides--no curves
You can cut a round cake into eight parts with three cuts, but you can't cut a circle into eight parts with three straight lines.

If you are talking about straight lines, the answer is NONE, because that is what noncollinear means. If curves are allowed, then the answer is infinitely many.
Diagonals connect corners of a figure. If you try to connect two corners of a three sided figure, the lines you draw will exactly mimic the sides of the figure. Because of this, a three sided figure has no diagonals.
