Calculate Sum of the Interior Angles:

Interior Angle Sum = (n - 2) x 180°

Interior Angle Sum = (7 - 2) x 180°

Interior Angle Sum = (5) x 180°

Interior Angle Sum = 900°

Calculate the number of diagonals

Diagonals =	n(n - 3)
	2

Diagonals =	7(7 - 3)
	2

Diagonals =	7(4)
	2

Diagonals =	28
	2

Diagonals = 14

Calculate 1 vertex diagonals

1 vertex Diagonals = n - 3
1 vertex Diagonals = 7 - 3
1 vertex Diagonals = 4

Calculate 1 vertex triangles

Triangles = N - 2
Triangles = 7 - 2
Triangles = 5

Determine polygon type

Since the polygon has 7 sides, it is a heptagon
