How many lines of symmetry does a parallelogram have and how???

A parallelogram has rotational symmetry of order 2 (through 180°). If in case it  has two lines of reflectional symmetry then it must be a rhombus or an oblong rather than a random parallelogram ..

A parallelogram has 0  line of symmetry . You can draw no such line in which they are congruent to each other. You can try it on paper to see that it has no line of symmetry .

Hope this would have cleared your doubt.

thank u priya

But in textbook NCERT answers(page 270 Q 7g it is given 0 and page 273 for rotational it is  order 1.I think it should be  1 and 2 for linear and rotaional respectively.Please explain

  • -1

Sorry, it should be 2 & 2 for both

 a parallelogram has 0 lines of symmetry since it has a kite like shapes

Many people think that a parallelogram has four lines of symmetry. But a parallelogram has no lines of symmetry. A line of symmetry is a line through which if we fold, the two halves will overlap each other exactly, in other words, the two halves will be congruent. But in a parallelogram, the two halves will not overlap each other exactly. You can try this out yourself by cutting out a parallelogram from a piece of paper and fold it in half.

Hope this clears your doubt,

             No pratu you are rong because se this diagran it is of parellolgram it has two lines of symmetry because u can take a paper and cut it into PARALLELOGRAM shape so it has 2 lines of symmetry

a parallelogram has 4 lines of symmetry

  • -2

A parallelogram has no sides of symmetry because its not a rhombus (slanting square) but it is a parellelogram (slanting rectangle).

it has no lines of symmetry because well if you slant the mirror,then it would be two.because it's paralellograms theory
