# How do you find the axis of symmetry?

The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=b2a .

## What is the axis of symmetry examples?

The two sides of a graph on either side of the axis of symmetry look like mirror images of each other. Example: This is a graph of the parabola y = x2 4x + 2 together with its axis of symmetry x = 2. The axis of symmetry is the red vertical line.

## How do you find the vertex and axis of symmetry?

The Vertex Form of a quadratic function is given by: f(x)=a(xh)2+k , where (h,k) is the Vertex of the parabola. x=h is the axis of symmetry.

## What is axis of symmetry in shapes?

The axis of symmetry is a straight line that makes the shape of the object symmetrical. The axis of symmetry creates the exact reflections on each of its sides. If we fold and unfold an object along the axis of symmetry, the two sides are identical. The axis of symmetry can be either horizontal, vertical, or lateral.

## What is simple axis symmetry?

Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror-like reflection of either side of the object.

## What is axis of symmetry for Class 6?

Answer: The axis of symmetry of a figure divides the figure into two equal parts.

## How do you find the axis of symmetry in intercept form?

So the equation for the axis of symmetry can also be written as where p,q are the x-intercepts. For example, y=(x-2)(x+4). The zeros are x=2,x=-4. The average of the zeros is (2-4)/2=-1, so the axis of symmetry is x=-1.

## What is the vertex formula?

What is the Alternative Formula used to Find the Vertex? The vertex formula to find the vertex coordinates (h,k)= (-b/2a, -D/4a) from the standard equation y = ax2 + bx + c, where D = b2 – 4ac.

## What is symmetry and axis of symmetry?

Axis of Symmetry. An axis of symmetry is a line about which a figure is symmetrical. If a figure can be folded such that the two parts exactly match, the fold line is an axis of symmetry. A figure can have one line of symmetry, many lines of symmetry, or no lines of symmetry.

## What is the axes of symmetry of a square?

Thus a square has four axes of symmetry, because there are four different ways to fold it and have the edges all match.

## What do you call axis of symmetry of line segment?

Answer: perpendicular bisector. Step-by-step explanation: i guess. hope it helps you.

## What is symmetry in math grade 6?

Symmetry means balance or form. Shapes, things or figures which have evenly balanced proportions are called symmetrical. A shape is symmetrical when its two halves are mirror images along the line of symmetry.

## What is symmetry in maths for Class 7?

If two or more parts of a figure are identical after folding or flipping then it is said to be symmetry. To be symmetrical the two halves of a shape must be of same shape and size. If the shape is not symmetrical then it is said to be asymmetrical.

## Where is the axis of symmetry in (- 3 2?

If the vertex of a quadratic equation is (-3,-2), and the line of symmetry is a vertical line that goes through the vertex, it must be x=-3.
