How do you 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.

What is an example of a line of symmetry?

Line symmetry,is also known as reflection symmetry. Other examples of shapes that have at least one line of symmetry include a square, with four lines of symmetry, and an equilateral triangle, with three lines of symmetry.When one half of an object is the reflection of the other half, the object is said to have line or reflection symmetry.

What are two lines of symmetry?

An oval has two lines of symmetry. A line of symmetry is defined as the line that a figure can be divided into half, with the end result of the two halves matching up exactly. Each side of the divided side looks like a mirror image. An oval figure can be divided down the middle,...

How many lines of symmetry?

A line of symmetry divides an object into perfectly matching sides. Therefore, a rectangle only has two lines of symmetry because it cannot be divided diagonally to create two matching sides. A triangle, on the other hand, has three lines of symmetry, as it can be divided through each point and through the middle of the other side three times.
