Is Egg an ellipse?
At high school we learn about ellipses, which are circles stretched sideways and their curve is determined as a constant sum of the distance to two foci (or fixed points). Eggs are neither circular nor elliptical. Eggs are oval. If you observe an egg closely, the distance from the center is not a fixed circle.

What are ellipses in drawing?

Since there are many objects that are circular in shape, ellipses will be used quite frequently in our drawings and paintings. Any circular shape can cause issues for an artist.
What is a true ellipse?
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.
