How do I find the line of symmetry?
How do I find the line of symmetry?
To find the line of symmetry algebraically, you need to identify if the equation is written in standard form or vertex form. Standard form is y = ax^2 + bx + c, where a, b, and c equal all real numbers. You can use the formula x = -b / 2a to find the line of symmetry.

What is an example of a line of symmetry?
For example, if we cut an apple in two equal halves, then the piece of apple is said to be in symmetry with another. One more good example is to imagine if we cut an equilateral triangle into two equal halves, then the two triangles formed after the intersection is the right-angled triangles.
How do you find the equation of a line?
To find an equation of a line given the slope and a point.
- Identify the slope.
- Identify the point.
- Substitute the values into the point-slope form, y − y 1 = m ( x − x 1 ) .
- Write the equation in slope-intercept form.

Which axis is the line of symmetry?
y-axis
The line (or “axis”) of symmetry is the y-axis, also known as the line x = 0. This line is marked green in the picture. The graph is said to be “symmetric about the y-axis”, and this line of symmetry is also called the “axis of symmetry” for the parabola.
What are symmetries in math?
Symmetry is a type of invariance: the property that a mathematical object remains unchanged under a set of operations or transformations. Given a structured object X of any sort, a symmetry is a mapping of the object onto itself which preserves the structure.
How many lines of symmetry A line has?
a line segment has infinite lines of symmetry all passing through its mid point irrespective of the angle it is making with the segment.

How do you determine the line of symmetry?
Line symmetry occurs when two halves of a figure are mirror images of each other when reflected across a line. • The line of symmetry is the line which divides the figure into two mirror images. • To determine if a figure has line symmetry, fold the figure along the supposed line of symmetry to see if the two halves coincide.
What is the equation of the line of symmetry?
Follow 4 steps to use an equation to calculate the line of symmetry for y = x2 + 2x. Identify a and b for y = 1×2 + 2x. a = 1; b = 2. Plug into the equation x = -b/2a. Simplify. The line of symmetry is x = -1.
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.
How do you calculate the axis of symmetry?
Plug your numbers into the axis of symmetry formula. To calculate the axis of symmetry for a 2nd order polynomial in the form ax2 + bx +c (a parabola), use the basic formula x = -b / 2a.
