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.
PARALELLOGRAM
Only an equilateral triangle has rotational symmetry.
An isosceles triangle
An isosceles triangle has only one line of symmetry
The Isosceles triangle only has one possible line of symmetry; and that is through the vortex, AKA: The middle, in a vertical line.
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.
