In the coordinate plane, the graph of an equation can have symmetry about the x-, y-axis, or some other line. x-axis symmetry. A graph is said to have x-axis symmetry if whenever the point, (x, y), is on the graph, then (x, -y) is also on the graph. y-axis symmetry. A graph has y-axis symmetry if whenever the point (x, y) is on the graph, then ...
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.
Here we can see that the y -axis is a line of symmetry because the graph would be symmetrical for each point of the curve. This is a really useful tool when drawing quadratic graphs because each point on the curve will be symmetrical with another.
A figure can have one or more lines of line symmetry depending on its shape and structure. For a parabola with quadratic equation y = ax 2 + bx + c, line of symmetry is x = -b/2a. ☛ Related Articles

You can find if a shape has a Line of Symmetry by folding it. When the folded part sits perfectly on top (all edges matching), then the fold line is a Line of Symmetry. Here I have folded a rectangle one way, and it didn't work .
May 15, 2024 · Line of Symmetry: A line of symmetry, also known as an axis of symmetry or mirror line, is a line that splits a shape or object into two identical and symmetrical halves. Each half mirrors the other, making them look like reflections of one another across the line which indicates that both parts of the shape would perfectly match.
