An object or image that best illustrates radial symmetry is a snowflake. But, a snowflake is not perfectly symmetrical; it only appears to be perfect to the naked eye.
a jellyfish is an example(:
A liver fluke has bilateral symmetry because it has a mirror image if you cut it in half.
When the object is located at the 2F point, the image will also be located at the 2F point on the other side of the lens. In this case, the image will be inverted (i.e., a right side up object results in an upside-down image). The image dimensions are equal to the object dimensions. A six-foot tall person would have an image that is six feet tall; the absolute value of the magnification is exactly 1. Finally, the image is a real image. Light rays actually converge at the image location. As such, the image of the object could be projected upon a sheet of paper.

1. Image is upright 2. Image is virtual 3. Image is of same size as object 4. Image is laterally inverted 5. Distance from object to mirror is equal to the distance from the mirror to the image
It means that the image cannot be seen on the screen.

Not sure what you are referring to.Radial symmetry? Objects with radial symmetry can be rotated in a plane and appear the same. Starfish have radial symmetry.Compared to bilateral symmetry where the object is the same or a reflection of itself down a centre line. Humans are approximately bilaterally symmetrical.Words that are the same in each direction are called palindromes. Mum, mom, abba, deed, kayak, deified, sexes, civic...
radial symmetry: the condition of having similar parts regularly arranged around a central axisCite:"radial symmetry." Merriam-Webster Online Dictionary. 2008. Merriam-Webster Online. 15 November 2008
No. An object/image has symmetry if you can draw a straight line through it and both sides are symmetrical (where the image looks the same on both sides of the line of symmetry.) There is no angle that you can place a line on the capital letter 'L' and get symmetrical images.
radial symmetry which means that all the parts of the body are arranged around a central axis in such a way that any plane passing through the central axis divides the animal in halves that are almost mirror image of each other
The definition of a line of symmetry is a line that can be draw down the center of any shape or object to show mirror image of the other side. where each side is a mirror image of the other side.
It can be thought of rotational symmetry along the axis
Radial SymmetryRadial symmetry is rotational symmetry around a fixed point known as the center. Radial symmetry can be classified as either cyclic or dihedral.Cyclic symmetries are represented with the notation Cn, where n is the number of rotations. Each rotation will have an angle of 360/n. For example, an object having C3 symmetry would have three rotations of 120 degrees.Dihedral symmetries differ from cyclic ones in that they have reflection symmetries in addition to rotational symmetry. Dihedral symmetries are represented with the notation Dn where n represents the number of rotations, as well as the number of reflection mirrors present. Each rotation angle will be equal to 360/n degrees and the angle between each mirror will be 180/n degrees. An object with D4 symmetry would have four rotations, each of 90 degrees, and four reflection mirrors, with each angle between them being 45 degrees.Bilateral SymmetryBilateral symmetry is symmetry across a line of reflection. Are people symmetric? We think we are, but upon closer analysis, we are less symmetric than we think. The more simple the creature (ants --> elephants), the more likeley it is that it will be perfectly symmetric.We took two professors, cut and pasted half of their head in Photoshop, and flipped that half horizontally. We then aligned the two halves so that it came closest ro resembling a human head. You be the judge on how good of a job we did and how symmetric people around us are in general ...Asymmetrical SymmetryAsymmetry is the absence of, or a violation of, symmetry.
When you can cut the object in half and it will look like a mirror image of each side.
The property is Reflection Symmetry, Line Symmetry or Mirror Symmetry
Yes. The image associated with this answer illustrates the situation in the case of non-Euclidean space. For more examples, search the web for MC Escher's Symmetry artwork.
Reflection symmetry, reflectional symmetry, line symmetry, mirror symmetry, mirror-image symmetry, or bilateral symmetry is symmetry with respect to reflection
