Is it possible to have more than one vertical line of symmetry? Why???

No. Imagine the center of the polygon. It can only have one point where the vertical line of symmetry hits the center of the polygon. So only one.

Thank you Mr. Knights so mych. You explained it to me well.

No problem :D

contruct the rhombus bend be 5.6cm de 6.5 cm

No, it is not possible to have more than one vertical line of symmetry for a given object. This is because a vertical line of symmetry is a line that divides an object into two equal halves that are mirror images of each other. If there were more than one vertical line of symmetry, it would mean that the object has multiple ways to be divided into equal halves that are mirror images, which is not possible.

To determine if an object has a vertical line of symmetry, you can visually examine it or use a geometric approach. Visually, you can imagine folding the object along a vertical line and see if the two halves match perfectly. Geometrically, you can check if the coordinates of the points on one side of the object are symmetric with respect to the vertical line passing through its center.

In summary, having more than one vertical line of symmetry is not possible because it contradicts the definition of symmetry, which requires only two mirror image halves.
