An ellipse is a conic section, a curving line which is the path of a point that moves in such a way that the sum of its distance from two fixed points is constant.... so no - there are not 4 straight angles in an ellipse, nor any straight bits at all.
square
a Rhombus...
If you draw two lines intersecting, you'll see that they create 4 angles.
There are right angles, acute angles, obtuse angles, and straight angles.
No. A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel. The opposite angles not congruent.
Yes, Every shape does!! * * * * * Not true. A circle or an ellipse does not have an angle. Nor does a solitary straight line.
An ellipse does not have four straight lines; it is a smooth, continuous curve defined as the set of points where the sum of the distances to two fixed points (the foci) is constant. While you can draw tangents that touch the ellipse at various points, the shape itself is not composed of straight lines. However, one can inscribe a rectangle within an ellipse that has four straight sides, but that is separate from the ellipse itself.
right angles and straight angles
it is a parallelogram or a trapezoid
None; an ellipse is a smooth curve, not a line.
No it cannot. A polygon is a plane space enclosed by straight lines. An ellipse consists of a curved line, not straight lines.
A quadrilateral

No, polygons are made of straight, non-overlapping sides. An ellipse has curves.
Ellipse.
there are 4 types of common angles. right, obtuse, acute, and straight.
It could be a stretched circle - a bit like an ellipse except that an ellipse does not have straight lines.
