Question

1. true or false: each number of sides has only one polygon. (in other words, every input has only one output). true false

Explanation:

A polygon is defined by the number of its sides, and for a given number of sides (input), there is exactly one type of regular polygon (though irregular polygons can vary, but the question implies a functional relationship where each number of sides maps to one polygon conceptually, like n -sided polygon is unique in terms of the polygon's definition by sides). So each number of sides has only one polygon (in the sense of the polygon's classification by side count, so each input - number of sides - has one output - the polygon type defined by that side count).

Answer:

True
