"A heptagon's interior angles all add up to 900 degrees." ... So, for a square, you would end up with this formula: (n-2)180/; (4-2)180 = sum of angles; 2x180 = 360 degrees; and a triangle; (3-2)180 = sum of angles; 1x180 = 180 degrees; A Heptagon has 7 sides, so it is; (n-2)180/;

Notice that we arbitrarily chose one of the seven congruent triangles that we could have drawn joining the center of the figure to one of the sides of the heptagon. So if we were to add up all the angles of all seven triangles at the center, we would have a full circle: 360°.
