Does a rectangle have exactly one line of symmetry?
No, it has two.
What plane figure has one horizontal symmetry and one vertical line of symmetry and has rotational symmetry?
A rectangle is a possible candidate, as is an ellipse.
How many lines of symmetry does LINES have?
If the question refers to a single completely geometrically straight line of finite length in a plane, then a straight line will have two lines of symmetry. One symmetry line is perpendicular to the line being discussed and one symmetry line coincides with the line being discussed. The symmetry operation here is the one where every point of the figure is flipped perpendicularly across the symmetry line and the object is symmetric if that flipping produced exactly the same set of points. (Said differently, if flipping the set of points through a line produced an exact replica of the original set of points, then the like determining the flip is a symmetry line.) One level of complication occurs if the straight line which is the subject of the symmetry question is an infinitely long straight line. In such a case one symmetry line still coincides with the actual line, but all lines that are perpendicular to the straight line will be lines of symmetry. Thus, an infinitely long straight line has no single point as its "middle" and has an infinitely many symmetry lines consisting of all possible lines perpendicular to the original line.
How do you figure out lines of symmetry?
Think of the line of symmetry as a mirror (indeed try using a small hand rectangular hand mirror). a symmetry either side of a line is like a reflection of one side in the mirror.
What is a line of symmetry?
A line of symmetry divides a figure into two halves that are the mirror images of each other.Fold a square sheet of paper exactly in half. When you unfold the paper you will see the crease down the center. That is an example of a line of symmetry. Both sides of an object must be equal to be symmetrical. Let's do a construction taking off on this idea. You've probably already done it at one time or another.Fold that piece of paper, and take a pair of scissors and cut half a heart out of it using the crease as a line going down the "middle" of the heart. Unfold the finished construction. You'll have a heart and that fold you made in the paper is the line of symmetry for the figure. The line of symmetry divides any shape into mirror images.
Exactly one line of symmetry?

Is there a quadrilateral with exactly 1 line of symmetry?
Yes - some trapezoids can have one line of symmetry.
What geometric figure has only one line of symmetry?
Only One Line of SymmetryAn isosceles triangle only has one line of symmetry.
Can a figure have line symmetry and not rotational symmetry?
Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
Does a rectangle have exactly one line of symmetry?
No, it has two.
Which triangle has exactly one line of symmetry?
Isosceles
What plane figure has one horizontal symmetry and one vertical line of symmetry and has rotational symmetry?
A rectangle is a possible candidate, as is an ellipse.
Can a figure have more than one line of symmetry?
yes
Does an isosceles trapezoid have exactly one line of symmetry?
Yes
What is the definition of reflectional symmetry?
An image has Reflectional Symmetry if there is at least one line which splits the image in half so that one side is the mirror image of the other. Reflectional symmetry is also called line symmetry or mirror symmetry because there is a line in the figure where a mirror could be placed, and the figure would look the same.
How you define line of symmetry?
Line symmetry is another name for reflection symmetry. One half is a reflection of the other half. The line of symmetry is the line where you could fold the image and have both halves match exactly.
What 5 sided figure has one line of symmetry?
It is called "Pentagon"
