Yes. An isosceles triangle, for example, is symmetric about the bisector of its odd angle but has no rotational symmetry.
There are three elements of symmetry: 1-axis of symmetry It's a line which cuts the molecule into two equal halves. 2-plane of symmetry It's a plane which cuts the molecule into two equal halves (such as 'axis of symmetry' but axis is a line and here it's a plane). 3-center of symmetry It's a point in space that, if you draw a line from any part to it, and then extend the line beyond it, another atom will be encountered.
Something that is symmetrical along a line. Like you could fold it in half and it would be the same. Like a rorschach inkblot. A butterfly. A person. The other kind of symmetry is radial symmetry, which is symmetrical from a point. Like a starfish. I think things that are radially symmetrical are always also laterally symmetrical, but there could be some weird exception to that that I can't think of.
Insects have bilateral symmetry because if they had radial symmetry, they would have to be perfectly round. Bilateral symmetry is just when you cut something with a line of symmetry down the middle and both sides are symmetrical.

they can but not all shirts have a line of symmetry for example an assymetrical shirt doesnt have a line of symmetry
An isosceles triangle for example has only one line of symmetry
A rhombus (not square) for example.
A kite, for example.
Apples are symmetrical. However, they do not have a line of symmetry. This is an abstract concept which is not found in real objects.
A rainbow.
Shapes do not always have lines of symmetry. For example, if you have an irregular shape, it will not have a line of symmetry. I am quite certain though that all geometric shapes have a line of symmetry.
A real life example of a line is a road. Other examples of lines include ball courts, driveways, roof tops, and buildings.
The line of reflection in symmetry is the imaginary line that travels down the line of symmetry. For example, in a square, the line of reflection would be the line down the center of the square, and the line down the diagonal of the square.
A real life example of a line is lines painted on the roadways. These lines divide traffic. Lines are also found on graphic prints and sport fields.
