One billion-sided polygon = GIGAGON
A 4-sided polygon has 2 diagonals. A 5-sided polygon, 5. 6-sided, 9. By induction, an n-sided polygon has 'n*(n-3)/2' diagonals. "n" is how many sides a shape has. so, (7)*(7-3)/2 now we have, 7*4/2 so, 28/2 = 14 Therefore, a 7-sided polygon would have 14 diagonals.
A triangle is classified as a 3 sided polygon.
A 10-sided polygon is a decagon.
A pentagon and a quadrilateral, respectively.

A triangle is a 3 sided polygon
An isosceles triangle is a 3 sided polygon.
There are 3 triangles inside a 5 sided pentagon polygon
The 3 interior angles of a 3 sided polygon which is a triangle add up to 180 degrees
A 3-sided polygon
A triangle is a polygon, though trigon is an alternative name for a 3 sided polygon.
The sum of the three INTERIOR angles is 180 degrees. And a 3-sided polygon is often referred to as a 'Triangle'.
