Circle
- Even though a circle isn’t a polygon, it is still a 2D shape. As long as the line of symmetry goes directly through the centre of the circle, it has unlimited lines of symmetry!

Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.
Jun 15, 2022 · Lines of Symmetry: Lines of symmetry are the lines that can be drawn to divide a figure into equal halves. Reflection: A reflection is a transformation that flips a figure on the coordinate plane across a given line without changing the shape or size of the figure. Symmetry: A figure has symmetry if it can be transformed and still look the same.
Look at the following pictures and observe. Observe that for each of the above figures, the one half on one side of the dotted line is exactly identical to the one half on the other side of the dotted line. When we fold these figures along the dotted line, one half of the figure would fit exactly over the other half.
1. Symmetry of a Line: A line has indefinite length and it can be considered that each line perpendicular to the given line divides the line into two equal halves. So a line has infinite symmetrical lines which are perpendicular to it. Also a line is symmetrical to itself. 2. Symmetry of a Line Segment:

A line of symmetry is defined as an imaginary line that divides an object into two identical (symmetrical) halves. Another way to think about this is: if a figure can be folded over a line such that each half perfectly overlaps, the line is a line of symmetry. In the above figure, folding the left half of the square over the red dotted line results...
Generally, there are a few different types of lines of symmetry: vertical, horizontal, and diagonal.
An object can have multiple lines of symmetry. If an object has multiple lines of symmetry, all the lines of symmetry intersect at the center of the object. Consider the following two-dimensionalshapes.
In the coordinate plane, the graph of an equation can have symmetry about the x-, y-axis, or some other line.
Mathematically, a line of symmetry is a line of reflectionthat maps any point on the figure back to the figure. The line that cuts through the major axis of the ellipseabove is a line of symmetry. When A and B are reflected across it, they are mapped to A' and B', also on the ellipse. This is true for any point on the ellipse. Not all lines of refl...
Symmetric- A symmetric figure has at least one line that divides the figure into two identical parts such that reflecting half of the figure across the line will result in the reflected half perfec...Asymmetric- An asymmetric figure is a figure in which no line can be drawn such that it divides the figure into mirror images.The shapes or objects that are irregular and do not resemble each other when divided into two parts are called ASYMMETRIC. Such shapes do not have a line of symmetry. A scalene triangle, a parallelogram, and a trapezium are examples of shapes that have no lines of symmetry.
Aug 22, 2021 · A line of symmetry is a line that cuts a shape in half. The shape will look the same on both sides of the line of symmetry. We can mark lines of symmetry using a dashed line drawn on the shape. We can find lines of symmetry using a mirror.
