Exterior angles of a polygon have several unique properties. 360 div number of sides. Join learners like you already enrolled.

The sum of the angles of a hexagon six sides is equal to. Try this with a square then with some interesting polygon you invent yourself Note. If you know the exterior.

The interior and exterior angles of a polygon are supplementary. In a polygon an exterior angle is formed by a side and an extension of an adjacent side. Have Number of angles 36060 6.

A Polygon is any flat shape with straight sides. Hence all its exterior angles are to be measured in the same as well ie 60 degrees. How to derive the formula for the sum of the exterior angles or a polygon and the formula for one exterior angle of a regular polygon.

To calculate the sum of interior angles subtract two from the number of sides and multiply the result by 180 degrees. Master K-12 math with IXLs interactive program. Formula to find 1 angle of a regular convex polygon of n sides angle1 angle2 angle3 360.

The sum of exterior angles in a polygon is always equal to 360 degrees. As the sum of the exterior angle of a polygon is 360 degrees and each one measures 60 degrees we. Ad A math website kids love.
