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.
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.
Lines of symmetry are straight lines that divide a shape into two equal parts where one part is an exact reflection of the other. E.g. A rectangle has two lines of symmetry (LoS) shown below using a dashed line.
3 Αυγ 2023 · In mathematics, symmetry is the property that divides a geometrical shape into two identical halves. Heart shape, an equilateral triangle, and a rhombus are all examples of symmetry. Such shapes are called symmetric.
Symmetry defines that the shape is identical on both sides when it is divided by a line. The symmetry of different shapes, regular or irregular. Learn about the symmetry of shapes with examples at BYJU’S.
Learn and practice identifying lines of symmetry in shapes with interactive resources from GeoGebra. Identify and make figures with line symmetry. Identify the number of lines of symmetry in a figure and draw lines of symmetry.
28 Νοε 2022 · Write down the number of lines of symmetry. The only line of symmetry is shown below. Answer = 1. Shade exactly 4 more squares so that the shape has 4 lines of symmetry. The shape below has a horizontal, a vertical, and 2 diagonal lines of symmetry. What is a plane of symmetry? If you’re unsure in the exam, consider the properties of the 3D shape.
