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.
Here you will learn about lines of symmetry, including symmetry properties within polygons, angle properties, and symmetry of different line graphs. Students first learn about line symmetry in grade 4 with their work with 2D shapes in geometry.
3 sie 2023 · The line of symmetry is an imaginary line that divides a shape or an object into identical halves. It is also called the axis of symmetry or the mirror line since it divides the figure symmetrically. The diagram below shows how a line of symmetry divides a shape into identical halves that are mirror images.
Line symmetry is a type of symmetry where one-half of the object reflects the other half of the object across the line. In simple words, we can say that when an object is divided into two equal parts with a line, then the two sides of the line look the same.
This Maths article shows how to find lines of symmetry on shapes and practise drawing them.
Learn about the different types of symmetry: Reflection Symmetry (sometimes called Line Symmetry or Mirror Symmetry), Rotational Symmetry and Point Symmetry.
Mathematically, a line of symmetry is a line of reflection that maps any point on the figure back to the figure. The line that cuts through the major axis of the ellipse above is a line of symmetry. When A and B are reflected across it, they are mapped to A' and B', also on the ellipse.
