Sometimes you can fold a shape in half, and if it fits into itself perfectly with no overlaps you have found a line of symmetry. Some shapes have more than one line of symmetry. Let's look at some ...

Plug in the values into the formula, and you get: The parabola's axis of symmetry (x = h) is a vertical line passing through the vertex, so as demonstrated above, this is x = 1. From the focal ...

According to the new study, bilateral symmetry—where there is only one line that divides the flower into two equal halves—has evolved and been lost multiple times independently in sunflowers ...
