Which quadrilateral sometimes has a line of symmetry but not all the time?
A trapezoid is a quadrilateral that sometimes has a line of symmetry but not always. A trapezoid can have a line of symmetry if it is an isosceles trapezoid, where the non-parallel sides are congruent. However, in a general trapezoid where the non-parallel sides are not equal in length, there is no line of symmetry. This distinction is important in understanding the properties of different types of quadrilaterals.
If it has exactly two lines of symmetry it must be a quadrilateral?
Not at all. There are an infinite number of figures that have two lines of symmetry. For a start, an ellipse.
Do all regular polygons have line symmetry?
yes
Do all polygons have rotational and line symmetry?
Yes.
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 shirts have a line of symmetry?
they can but not all shirts have a line of symmetry for example an assymetrical shirt doesnt have a line of symmetry
What quadrilateral has two lines of symmetry bit not all sides are equal?
A rectangle.
What is the symmetry for all quadilaterals?
Well, a quadrilateral automatically has 4 sides and 4 angles that equal 360 degrees. Past that, a quadrilateral can be anything at all!

Not at all. There are an infinite number of figures that have two lines of symmetry. For a start, an ellipse.
Shapes with no line of symmetry?
All regular shapes have a line of symmetry. But you can get rid of its line of symmetry by making it irregular (so the angles aren't the same).
Does every figure have a line of symmetry?
Shapes do not always have lines of symmetry. For example, if you have an irregular shape, it will not have a line of symmetry. I am quite certain though that all geometric shapes have a line of symmetry.
Which letters of alphabet have no line symmetry?
all letters have a line of symmetry
Do all figures have a line of symmetry?
no
Is it possible for a quadrilateral to have three lines of symmetry?
It can't have exactly three (it can be a square and have four). Reflecting about a line of symmetry swaps at least two corners of the quadrilateral: a corner has to be symmetric to a corner, and if all four were symmetric to themselves, they'd all have to be on a line, which is impossible. Moreover, different lines of symmetry swap different pairs of corners. Once you pick two corners, there is only one line of symmetry which could possibly swap them - the perpendicular bisector of a segment drawn between the two corners. If two different corners are symmetric, that means that their angles are equal. So three lines of symmetry means that there are three pairs of corners with equal angles. Since there are only four corners total, the only way for this to happen is for all four corners to have equal angles. Then it's either a rectangle (which doesn't work - only two lines of symmetry) or a square (which has four lines of symmetry). Neither possibility has exactly three.
Do all quadrilaterals have at least one line of symmetry?
Not all 4 sided quadrilaterals have lines of symmetry.
Does a spoon have line symmetry?
yes it does. the line of symmetry goes down vertically from the top of the spoon all the way to the bottom
