What is the relationship between the number of triangles formed from one vertex and the number of sides of the polygon?

3

An expression for the sum of the interior angles in a polygon is 180(n - 2).
Match each of the parts of the formula with their meaning.

180		the sum of the angles in one triangle
n		the number of sides of the polygon
n - 2		the number of triangles formed by the diagonals from one vertex

1

Use the formula 180(n - 2) to calculate the sum of the interior angles of a hexagon. You should get 720°.

Hey you made it to the end! Don't forget ALEKS this week...

Draggable item		Corresponding Item
diagonal		an angle inside a shape
quadrilateral		the angle between any side of a shape, and a line extended from the next side
interior angle		a 2-dimensional shapes that is made of straight lines, and the shape is "closed"
exterior angle		line segments from one corner (or vertex) to another but not the edges
hexagon		a 4 sided shape
pentagon		a 5 sided shape
vertex		a 6 sided shape
polygon		a point where two or more line segments meet
