On this note, some letters keep their lines of symmetry even when made lowercase, no matter the font. Translational symmetry: If the object is moved or translated from one position to another, the same orientation in the forward and backward motion is called translational symmetry.

When an object is rotated in a particular direction, around a point, then it is known as rotational symmetry, also known as radial symmetry. If the sides match up, you can identify that the shape has a line of symmetry; if they dont, you can determine that the shape is asymmetrical. What makes a letter or object symmetrical?

In other words, objects are the same on both sides of a line (usually in the middle). This means you can draw a mirror line down through the middle of each shape and divide it into two reflected halves. With two-dimensional shapes, you can find a line of symmetry by folding the image/object until both sides of the shape are completely aligned with one another. These explanations are written by Lido teacher so that you easily understand even the most difficult concepts. What letters have vertical line symmetry?
