The DUCK SHOOT game to practice
'Sum of interior angles' for 8th grade

Polygons: calculate the sum of interior angles from the number of sides

Any polygon with more than 3 sides can be split into a series of triangles by drawing lines between corners. Since we know that the interior angles of triangles sum to 180°, we can calculate the sum of the interior angles of any polygon by multiplying the number of triangles it contains by 180°. A shorthand version of this calculation is to take 2 away from the number of sides of a polygon and multiply that number by 180°.

The formula for calculating the sum of interior angles of a polygon given the number of sides is:

Sum of interior angles = (N - 2) x 180°

(where N = Number of sides and 180° = sum of interior angles of a triangle)

So, for any polygon with 5 sides (pentagon), the interior angles sum to:

3 x 180° = 540°

For a polygon with 10 sides (decagon), the interior angles sum to:

8 x 180° = 1440°

For a polygon with 3 sides (triangle), the interior angles sum to:

1 x 180° = 180°

With our Duck shoot math game you will be practicing the topic "Sum of interior angles" from 8th grade / Geometry & measures / Polygons / Polygons. The math in this game consists of 16 questions that ask you to calculate the sum of the interior angles for each of the given polygons.

Large thumbnail for math game Duck shoot

DUCK SHOOT is a fun game to learn math where you attempt to knock over all the fairground ducks in each level. In the first level there are only 6 ducks but by level 10 there are 24 fast moving "quackers quacking"...

After each level, win an additional 20 points by correctly answering a math question from your selected topic. There is no timer in this game: take as long as you like to answer the math questions correctly for a best score to get you on the DUCK SHOOT leaderboard.
