sum of interior angles


Find the other angles, then find the sum.


What is the sum of the interior angles for the graph above? Is it the same for all quadrilaterals?

One square. Separate the triangles. If a triangle makes 180º, two triangles makes a square and a sum of 360º.

Given the pentagon below, how many triangles can be made from it?

knowing that the angles in a pentagon sum up to 540º,

what do you think the equation for the sum of interior angles is?

Number of angles.

What would be the equation to find the number of angles given the sum?
