For a 7 sides polygon which is called heptagon or septagon Interior angles = (7-2)*180/7 = 128.57° Exterior angle = 180 - 128.57 = 51.43° Central angle = 360/7 = 51.43°
The statements which are correct:
<span>3. The regular polygon ABCDEFG can be broken down into 2 isosceles trapezoids and 1 isosceles triangle </span> <span>5. The central angle of the polygon ABCDEFG is about 51.43° and each interior angle is about 128.57° </span> <span>7. The central angle ABCDEFG is the same measure of the exterior angle
</span>
