The shape you are referring to is called a "quadrilateral." A quadrilateral is a polygon with four sides and four vertices. It can have various combinations of straight and curved sides, including two straight sides and two curved sides. Examples of quadrilaterals with two straight and two curved sides include a kite or a concave quadrilateral.
The two foci are necessary to define the location of an ellipse, but the shape depends on the eccentricity, which is related to the lengths of the two axes.
Is called a leg.
The major axis is the line that joins the two foci (focuses) of the ellipse. If all you have is a picture of an ellipse and you don't know where the foci are, you can still find the major axis in a few seconds: It's the longest possible line that you can draw completely inside the ellipse, and it's the line straight across the ellipse between the two opposite "points of the egg".
The question asks about four sides and 2 perpendicular sides. That makes 6 sides in all. So it is a hexagon with either only one right angle, or two sides that are mutually perpendicular.
