Properties So what can we know about regular polygons? First of all, we can work out angles. Exterior Angle The Exterior Angle is the angle between any side of a shape, and a line extended from the next side. All the Exterior Angles of a polygon add up to 360°, so: Each exterior angle must be 360°/n (where n is the number of sides)

Yes. The blunt end of an egg has an air pocket between the inner and outer shell membranes. This gradually enlarges as the egg loses moisture during storage. Keeping the air pocket at the top helps to keep the yolk centred within the egg and prevents the air pocket from rupturing, which reduces the risk of the egg spoiling.

The egg is developed in a chicken via the Oviduct but only stays there for about 24 hours, the balance of the development is done outside the hens body after the egg is laid by the hen.
