Find the other angles, then find the sum.

## Quadrilaterals

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?

## Number of angles

Given that the sum is 1260º, how many angles are there?
