A. Flatworms were the first organisms to exhibit bilateral symmetry.
Arial symmetry
Yes, it is possible to have a shape that has a line of symmetry but does not have rotational symmetry. An example is the letter "K", which has a vertical line of symmetry but cannot be rotated to match its original orientation.
Bi-Lateral.
A sea urchin has radial symmetry, meaning it is symmetrical around a central axis, like a wheel. This symmetry allows them to have multiple planes of symmetry passing through the central axis, giving them equal parts around the center.

Symmetry in animals is something that is very important. It is a big part of classification in animals. Nearly all multi-cellular organisms exhibit one or other type of symmetry such as radial or bilateral. For more on this see the source.
The word that fits the clues is "H." It has both horizontal and vertical symmetry, as it looks the same when flipped along either axis. In contrast, the letter "Q" has vertical symmetry but no horizontal symmetry, while the letter "O" exhibits horizontal symmetry but no vertical symmetry.
equilateral triangle
Yes, it is possible for a shape to have at least one pair of parallel lines and no lines of symmetry. For example, an irregular trapezoid has one pair of parallel sides but lacks any lines of symmetry due to its uneven angles and side lengths. This demonstrates that parallel lines and symmetry are independent properties in geometric shapes.

There are lots of really good websites that will help you to understand the symmetry worksheets.I recommend that you try the following websites,www.mathsisfun.com/ and www.superteacherworksheets.com/symmetry.html.
The reflexive property, which is a property of all equivalence relations. Two other properties, besides reflexivity, of equivalence relations are: symmetry and transitivity.
The letter "H" has 2 lines of symmetry: one vertical line through the center and one horizontal line through the middle. Its order of rotational symmetry is 2, meaning it looks the same after a rotation of 180 degrees.
