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.
Line symmetry is a type of symmetry where one-half of the object reflects the other half of the object. Learn how to recognize line symmetry with concepts, definitions, and examples.
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.
Sep 24, 2024 · Lines of Symmetry. The lines of symmetry are the imaginary lines along which a geometrical figure is symmetric in nature. We can classify the lines of symmetry in two types. First one is based on the nature of lines of symmetry which can be further classified as horizontal, vertical or diagonal in nature.
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.
Printable & Online Geometry Worksheets. What is symmetry? A line of symmetry is an imaginary line that divides a figure in half. If you fold a figure along a line of symmetry, both sides match. Symmetry is found in nature, in art, in common objects, in letters and more. Symmetry is also referred to as mirror image. Show Video Lesson.
Solved Examples on Symmetry. Example 1: How many lines of symmetry does the given figure have? Answer: Only one line of symmetry. Example 2: Can you find any examples of letters from the alphabet that have a horizontal line of symmetry? Answer: A lot of letters, like O, D, H, have horizontal lines of symmetry. Example 3: Is the given shape ...
