What is the line of symmetry for the letter E?
A horizontal mirror plane though the the middle line of the E
How does numerical value of e change as shape of ellipse approaches straight line?
"e" will get greater. The eccentricity for a line is one and for a circle is zero. Since it is getting closer to becoming a line it will go up in value. ; ) "e" will get greater.

Is D e and H collinear?
You need a diagram to tell. Remember, collinear means in a line. If D,e, and H can all be connected by a straight line, then yes, they are collinear.
Why do you use two arrowheads when drawing or naming a line such as EF?
In Geometry, lines go on to infinity in both directions. This is why arrows are used. The two letters, E and F define that line. Of course if you were to measure the distance from E to F, that would be a line segment or part of the line.
What is the difference between line of reflection and line of symmetry?
a line of symetry can be applied to one shape but cannot go between two shapes unless those two shapes are infact a part of one larger, symetrical shape. a line of reflection goes between two shapes. so O l O this is two circles with a line of reflection in between them. if there was a line of reflection between two e's then one of the e's would have to be a backwards e.
