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.
Definition. Symmetry : The dotted line divides the figure into two identical parts. When the figure is folded about this line the two parts fir exactly over each other. Such a figure is said to be Symmetrical. Axis of Symmetry : THe line that divides the figure into two identical parts is called Axis of Symmetry.

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 ...
Example 1: the equilateral triangle. Draw all of the lines of symmetry for the equilateral triangle below: Locate the centre of the 2D shape. Draw a small x x in the centre of the triangle: 2 Use a ruler to visualise a horizontal and/or vertical line of symmetry through the centre of the shape.
Aug 3, 2023 · In geometry, the number of lines of symmetry varies according to the shape as shown in case of polygons. In triangles, the line of symmetry can be one, three, or zero, depending upon its type. In quadrilaterals, the line of symmetry can be one, two, four, or zero based on the shape.
In the coordinate plane, the graph of an equation can have symmetry about the x-, y-axis, or some other line. x-axis symmetry A graph is said to have x-axis symmetry if whenever the point, (x, y), is on the graph, then (x, -y) is also on the graph.
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.
