That might be a figure as simple as a triangle, as long as it is no special triangle (that is, a triangle with sides of three different lengths).
parallegram
Rotational symmetry.
square
Pentagon
2 lines of symmetry
First of all it is 'polygon' NOT 'polgon'. A five sided shape is named a 'pentagon'. Here is a list for up to 10 sides. 3- trigon (triangle) 4- quadragon ( quadrilateral 5- pentagon 6- hexagon 7 - heptagon 8- octagon 9- nonagon 10 - decagon 100 sides - a centagon. '--gon' is the name for a 2-dimensional shape '--hedron' is the name for a 3-dimensional object.
It is a triangle
Icosogon
Heptagon
If it is a square or a rectangle, then yes, it will have lines of symmetry. But if you're thinking of your typical parallelogram that does not have another name, then no, it does not have lines of symmetry. Basically, no.
ABCDEFG, F and G
A nephroid has 2 lines of symmetry.
