What is a line of symmetry in math?
What is a line of symmetry in math?
A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly. An equilateral triangle has 3 lines of symmetry.
How do you find a line of symmetry?
Folding Test 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.
What is symmetry and line of symmetry?
We say there is symmetry when the exact reflection or mirror image of a line, shape or object gets created. 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.
What is a line of symmetry in a triangle?

Triangle/Line of symmetry
How did you get the line of symmetry in each figure?
When you can divide a figure or an object into two even matching halves, you say that the figure has line symmetry. This figure can be divided in one way, vertically. If you tried to divide it horizontally, the two sides would not match. You can divide it vertically and horizontally and both sides will match.
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.
What is a shape with no lines of symmetry?
Two shapes that have no lines of symmetry are the scalene triangle and an irregular quadrilateral.
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 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,…
What does a symmetry line look like?
Symmetry is when a figure has two sides that are mirror images of one another. It would then be possible to draw a line through a picture of the object and along either side the image would look exactly the same. This line would be called a line of symmetry.
What is a diagonal line of symmetry?
Basically, a line of symmetry is a line that divides a figure into two mirror images. The figure is mapped onto itself by a reflection in this line. But the diagonal line is NOT a line of symmetry.
