Example 3: using angles. Show that the hexagon below has no lines of symmetry. Locate the centre of the 2D shape. Show step. Draw a small x x in the centre of the hexagon (this does not have to be exact): Use a ruler to visualise a horizontal and/or vertical line of symmetry through the centre of the shape. Show step.

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.1 Line symmetry about the y-axis means that for every point (x, y) on the graph, there is a corresponding point (-x, y). This indicates that the left side of the graph is a mirror image of the right side
4 Draw a line from each vertex through the center and check for line symmetry. 5 State the number of lines of symmetry. The equilateral triangle has 3 3 lines of symmetry. An equilateral triangle has 3 3 equal sides and 3 3 equal angles, so it will have 3 3 lines of symmetry.
Graph A: This graph is symmetric about its axis; that is, it is symmetric about the line x = 3. There is no other symmetry. This graph shows a function. Graph B: This graph is symmetric about the axes; that is, it is symmetric about the lines x = 0 (the y -axis) and y = 0 (the x -axis). It is also symmetric about the origin.
Aug 3, 2023 · A graph is symmetric about the y-axis when the points (x, y) and (-x, y) are present on the same graph. A graph will have y-axis symmetry if we get an original equation to the original one when we replace x with –x. Let us test the symmetry of a graph with the equation y = x 4 +3x 2. x-axis symmetry test: replacing y with –y:-y = x 4 +3x 2 ...

The line of symmetry also known as a mirror line is a line that divides an object into two identical pieces. Here, we have a square and we can fold it into two equal halves. When a figure is folded in half, along its line of symmetry, both the halves match each other exactly. This line of symmetry is called the axis of symmetry.
