How would I find the line of symmetry?

Find the Line of Symmetry Graphically Find the vertex, which is the lowest or highest point of a parabola. Hint: The line of symmetry touches the parabola at the vertex. (-1,-1) What is the x -value of the vertex? -1 The line of symmetry is x = -1

How do you determine lines of symmetry?

Each parabola has a line of symmetry. Also known as the axis of symmetry, this line divides the parabola into mirror images. The line of symmetry is always a vertical line of the form x = n, where n is a real number. This tutorial focuses on how to identify the line of symmetry.

How to find lines of symmetry?

A line of symmetry can be found by folding the shape. If the shape can be folded in half, the line of the fold is a line of symmetry. We fold the shape over and if one half lies exactly on top of the other half, we have a line of symmetry. Lines of symmetry are lines that divide shapes in half.

What are the characteristics of line of symmetry?

The line of symmetry can be defined as the axis or imaginary line that passes through the center of the shape or object and divides it into identical halves. This opens in a new window. Here, for instance, if we fold the figure cut out exactly at the center vertically, its halves will be congruent. The line of the fold is the line of symmetry.
