A polygon is just a word used to describe any plane figure bounded by straight lines. A triangle is just one of many different polygons; others are a rectangle, pentagon, octagon etc.
Triangles are said to be similar when they have the same shape but one is an enlargement of the other. The triangles must therefore be equi-angular and the ratios of corresponding sides have to be equal.

Do two polygons which are similar have the same shape?
Similar polygons are polygons for which all corresponding angles are congruent and all corresponding sides are proportional. From this definition we can say they have the same shape.
