explain lines of symmetry?

Answer 1

a line that divides any shape or object into two mirror images
eg human body has a line of symmetry that cuts through the centre vertically

Answer 2

A line of symmetry is also called a fold line. When a shape is folded on the line of symmetry, both sides match. They are the same size and shape.

Answer 3

When any figure or an object is folded on a certain line, then that lines divides the figure or figure exactly. i.e. two parts are congruent.
e.g. A square is having axis of symmetry along the sides as well as along the axis. While a rectangle is having axis of symmetry along the sides only.
An equilateral triangle has 3 axis of symmetry along the three sides
But in isosceles triangle have only one axis of symmetry along the non-congruent side.
While in scalene triangle there is no axis of symmetry.
In case of circle there are infinite axis of symmetry.

Answer 4

Lines of symmetry are the lines which divide shapes in equal sizes . This also called 'fold lines' .

Answer 5

A line of symmetry is a line that can be drawn through a plane figure so the figure on one side is the reflection image of the figure on the opposite side..

Answer 6

I think 'fold lines'
If the shape can be folded so that both sides are an exact mirror of each other ... the fold line is the line of symmetry

Answer 7

It is the line which divides a figure in 2 equal parts such that both the parts are the mirror image of each other

Answer 8

Essentially, they are lines that divide a shape or object into two equal sides.

Answer 9

the lines which divide the given geometrical figure into two symmetrical parts (mirror images)
