Investigation: Total Interior Angle in a Polygon

Posljednje ažuriranje over 3 years ago

In this exercise, you will figure out a general rule to describe the sum of internal angles in a triangle.

Step 1:

Split each diagram into triangles in such a way that you are only splitting the angles at each vertex.

Step 2:

Use your understanding of the sum of the interior angles of a triangle to find the total interior angle of the shape in question.

Step 3:

Compare all the values of every shape and figure out a general rule for a polynomial of any number of sides.
