Do lines of symmetry have to be straight?
yes they do
Do all shapes have lines of symmetry?
not all shapes have lines of symmetry. one example is a triangle.
Do all octogons have the same number of lines of symmetry?
All regular octagons have the same number of lines of symmetry, but octagons with unequal sides would have fewer lines of symmetry.
Do all triangles have three lines of symmetry?
no, only equilateral triangles have 3 lines of symmetry
What trapezium doesn't have any lines of symmetry?
All trapeziums have no lines of symmetry unless it is an isosceles trapezium which has one line of symmetry
Do lines of symmetry have to be straight?
yes they do
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.

Are all quadrilaterals symmetrical?
Not all 4 sided quadrilaterals have lines of symmetry although some of them do have lines of symmetry.

How many lines of symmetry does the human body have?
the human body only has 1 line of symmetry straight down the middle
Has a triangle got 2 lines of symmetry and 2 lines of rotational symmetry?
First of all, your grammar is terrible. The question should be "Does a triangle have 2 lines of symmetry and 2 lines of rotational symmetry? and the answer is no. A triangle can not have 2 lines of rotational symmetry, because you only rotate the image, you do not use any lines.
How many number of lines symmetry for a regular pentagon?
1 straight down the middle
Does circles has exactly 2 lines of symmetry?
A circle has infinitely many points of symmetry. Every straight line that passes through the center of a circle is a line of symmetry.
