Angles in Polygons
Triangle has 3 sides and the sum of interior angles are 180 (180 x 1)
Quadrilateral has 4 sides and the sum of interior angles are 360 (180 x 2)
Pentagon has 5 sides and the sum of its interior angles are 540 (180 x 3)
Hexagon has 6 sides and the sum of its interior angles are 720 (180 x 4)
The exterior angles of a polygon add up to 360 degrees.
To find out what you have to times 180 by, just minus 2 from the amount of sides and voila!
If you were to walk around a polygon, by the time you got to where you started you would have made a full turn. That means all of the corners you…
