Question 1175260
yes.


the equation is that the sum of the internal angles is equal to (n - 2) * 180 where n is the number of sides in the polygon.


in a triangle, n = 3 and the sum of the internal angles is 1 * 180 = 180.


in a quadrilateral, n = 4 and the sum of the intenal angles is 2 * 180 = 360.


if the sum of the internal angles is 900, then the equation becomes:


(n - 2) * 180 = 900.


this simplifies to 180 * n - 360 = 900


add 360 to both sides of the equation to get 180 * n = 1260.


solve for n to get n = 7.


the polygon is a 7 sided figure.


i think that's called a heptagon.


here's more than you probably wanted to know about the names of polygons.
