It depends on the shape of the water melon, round, oval, etc. If it was oval there would probably only be 2 lines of symmetry - top to bottom and left to right. You can't go diagonal because it wouldn't be even. A circle has an infinite number of lines of symmetry. Any chord of the circle that passes through its center will be line of symmetry. And there are an infinite number of lines that can be drawn through the center of the circle. So if the water melon was a circle it would have an infinite amount of symmetry lines. Hope it helps!! :)
Circles and Ovals DO have lines of symmetry: a circle has an infinite number of them (each is a diameter of the circle) and an oval (ellipse) has two (one along the major axis, one along the minor axis). Shapes which have no lines of symmetry are irregular ones, eg scalene triangles, along with most parallelograms (ie parallelograms which are not rhombuses) and non-isosceles trapezia. Some irregular shapes can have lines of symmetry, eg irregular octagons can have 1, 2 or 4 lines of symmetry as well as no lines of symmetry, unlike a regular octagon which [always] has 8 lines of symmetry.
If you canfold something in half and the two sides are identical then the fold is a line of symmetry. A circle has an infinite lines of symmetry because you can fold it in infinite places and it will always be the same. An oval has two - you can fold it the long way or the short way.

Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
2 how to you not know that?Actually the answer is "one or more" - how do you not know that?
Koalas have bilateral symmetry, as all vertebrates do.

No it is a shape, but the shape has symmetry.
Ah, the beauty of symmetry! An oval has an infinite order of rotational symmetry because it looks the same no matter how much you turn it. Just like nature's wonders, the oval's graceful curves bring a sense of harmony and balance to our world.
draw an oval then if you want to make it look like its about to crack then go and draw triangular squiggly lines and or draw crooked lines
