Find the sum of the interior angles of convex polygons.

###### Supporting targets:

###### 1:

Identify the interior angles of convex polygons.

###### 2:

Explain that polygons have the same number of interior angles as sides.

###### 3:

Discover the Triangle Sum Theorem, which states that the sum of the measures of the interior angles in any triangle will always be 180°.

###### 4:

Use the Triangle Sum Theorem to make conclusions about the interior angles of other polygons.

###### 5:

Use understandings of the sum of interior angles of polygons to solve for an unknown angle measurement or a variable.
