- A 2D shape is symmetrical if a line can be drawn through it and either side is a reflection of the other. You would call this the line of symmetry. If you put a mirror on this line, you would see the whole shape in the reflection. That’s why a line of symmetry is sometimes called the mirror line.

Lines of symmetry are straight lines that divide a shape into two equal parts, where one part is an exact reflection or mirror image of the other. In geometry, many 2D shapes have line symmetry. For example,

The very first thing to check is that the object tends to have a reflection of one-half. Imagine folding a rhombus or square along each line of symmetry and each of the half matching up perfectly, then this is symmetry. Thus, a shapehas to have at least one line of symmetry to be considered as a shape with line symmetry or mirror symmetry. It is kn...
A square has 4 lines of symmetry, which are lines through the opposite vertices, and the lines through the midpointsof opposites sides make up the four lines of symmetry. So, a square has 1 vertical, 1 horizontal, and 2 diagonal lines of symmetry.
A rectanglehas two lines of symmetry, that is lines through the midpoints of opposites sides. When a rectangle is folded across its diagonals, the shape is not symmetrical. So, a rectangle has just 1 vertical and 1 horizontal line of symmetry.
The line symmetry in a triangledepends upon its sides. If a triangle is scalene, then it has no line symmetry. If a triangle is isosceles, then it has at least one line of symmetry, and if the triangle is equilateral, then it has three lines of symmetry.
Since an infinite number of lines can be drawn inside a circlepassing through its center, therefore a circle has an infinite number of lines of symmetry. In coordinate geometry, a parabola has a line symmetry and its line of symmetry passes through its vertex. For a parabola with quadratic equation y = ax2+ bx + c, the line symmetry equation is of ...
This page will helps you to understand the concepts of symmetry, lines of symmetry, types of symmetry along with example alphabets A to Z ,numbers 0 to 9 and major geometry shapes. Definition. Symmetry : The dotted line divides the figure into two identical parts.
You can find if a shape has a Line of Symmetry by folding it. When the folded part sits perfectly on top (all edges matching), then the fold line is a Line of Symmetry. Here I have folded a rectangle one way, and it didn't work .
Lines of symmetry in regular shapes. Many 2D shapes have lines of symmetry. Regular polygons all share the property that the number of sides is equal to the number of lines of symmetry. Below is a couple of examples of these cases:
A line of symmetry is the line that divides a shape or an object into two equal and symmetrical parts. We also call this line the axis of symmetry or mirror line because it divides the figure symmetrically, and the divided parts look like mirror reflections of each other.
Aug 22, 2021 · A line of symmetry is a line that divides a shape exactly in half. They are drawn with a dashed line. Lines of symmetry can be found by folding a shape in half or using a mirror.
