Yes, an isosceles triangle has one line of symmetry. This line of symmetry runs vertically down from the vertex opposite the base to the midpoint of the base, effectively dividing the triangle into two mirror-image halves. The two equal sides of the triangle reflect across this line, demonstrating its symmetry.
2 lines of symmetry
A nephroid has 2 lines of symmetry.
A parallelagram can be a square, which has four lines of symmetry or a rectangle which has two lines of symmetry but the generic parallelagram has zero lines of symmetry
A decagon need not have any lines of symmetry. It can also have 1 or 10 lines of symmetry.

An isosceles triangle consist of 3 straight lines 2 of which are equal in length
2 lines of symmetry
A nephroid has 2 lines of symmetry.
it has five lines of symmetry
Equilateral Triangles (3 lines of symmetry)Rectangles (at least 2 lines of symmetry)Squares (4 lines of symmetry)Rhombuses (at least 2 lines of symmetry)Any regular polygon (at least 5 lines of symmetry)
it has no lines of symmetry
A parallelagram can be a square, which has four lines of symmetry or a rectangle which has two lines of symmetry but the generic parallelagram has zero lines of symmetry
There is no such thing as 8 lines of symmetry. A circle, for example, has infinitely many lines of symmetry.
A decagon need not have any lines of symmetry. It can also have 1 or 10 lines of symmetry.
