Question

The sum of the measures of the interior angles of a polygon is 540��. classify the polygon by the number of sides. pentagon quadrilateral hexagon triangle

Answer 1

540/180=3+2=5 sides
It's a pentagon
Formula the sum of angles divide by 180 cuz a triangle equals 180 degrees then add 2.
Check below
So a 5 sided polygon known as a pentagon you subtract two. And it gives you 3 cuz it has 3 triangles in the pentagon that you can draw then 3 triangles times 180 = 540 degrees
