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,
Different types of Quadrilaterals (a 4-sided plane shape): A regular polygon has all sides equal, and all angles equal: And the pattern continues: ... A line (drawn at any angle) that goes through its center is a Line of Symmetry. So a Circle has infinite Lines of Symmetry.
Some symmetrical shapes have one line of symmetry, some have two and some have more than two, as shown below: (i) Examples of the shapes having one-line symmetry: One-Line Symmetry. Some shape may have two or more lines of symmetry like a circle has infinite lines of symmetry. A square has four lines of symmetry.
Some shapes have more than one line of symmetry. Let's look at some 2D shapes and their lines of symmetry. These are shapes that have all equal sides and equal angles. The number of lines of...
May 15, 2024 · In geometry, we have shapes with one or multiple line of symmetry as per its structure such as the square, rectangle, triangle, rhombus and parallelogram. These lines can be horizontal, vertical or diagonal.
Symmetry can be defined for both regular and irregular shapes. For example, a square is a regular (all sides are equal) and a rectangle is an irregular shape (since only opposite sides are equal). The symmetries for both shapes are different. Check different figures with symmetry here.
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.
