An isosceles triangle
The Isosceles triangle only has one possible line of symmetry; and that is through the vortex, AKA: The middle, in a vertical line.
An isosceles triangle has one line of symmetry, which is the vertical line that runs from the apex (the vertex opposite the base) down to the midpoint of the base. This line divides the triangle into two mirror-image halves. Unlike an equilateral triangle, which has three lines of symmetry, an isosceles triangle only has this single line due to its two equal sides.
PARALELLOGRAM
Only an equilateral triangle has rotational symmetry.

There is only one line of symmetry in an isosceles triangle. If you draw this triangle with the "odd" side as the base and then bisect it with a vertical line, you will have that one line of symmetry. The triangle can be folded in half along this line because each side is a mirror of the other.

It will have 3 lines of symmetry if its an equilateral triangle and only 1 line of symmetry if its an isosceles triangle.

An isosceles triangle
An isosceles triangle for example has only one line of symmetry
An isosceles triangle has only one line of symmetry
An isosceles triangle has only 1 line of symmetry.
An isosceles triangle has only one line of symmetry
None. An isosceles triangle has only one line of symmetry, while an equilateral triangle has three.
