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.
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.
Line of symmetry. A line of symmetry is a line that divides a figure into two identical parts. The figure below shows 3 line of symmetry examples. What is a line of symmetry. A line of symmetry is defined as an imaginary line that divides an object into two identical (symmetrical) halves.
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.
May 15, 2024 · Line of Symmetry Examples. Example 1. Find the axis of symmetry of the parabola y = -2x2 − 4x + 8. Solution: Given equation: y = -2x 2 − 4x + 8. Compare the given equation with the standard form ax 2 + bx + c. ⇒ a = -2, b = −4, c = 8. Use the formula of axis of symmetry = −b/2a. = − (−4)/2 (-2) ⇒ x = 1.
Sep 24, 2024 · Symmetry in mathematics refers to a balance or similarity in shape, size, or arrangement on both sides of a dividing line or point. It’s a fundamental concept used to analyze patterns and structures in mathematics.
Line of Symmetry is an imaginary line or axis used to obtain symmetrical halves. Learn types of the axis of symmetry, multiple lines symmetry and examples at BYJU'S.
