Depending on the triangle, there can be 0, 1, or three lines of symmetry. A scalene triangle (all sides of different lengths) will have no lines of symmetry, an isosceles triangle (exactly two sides of the same length) will have one line of symmetry, and an equilateral triangle (all three sides of the same length) will have three lines of symmetry.
The diagonals of a rectangle aren't lines of symmetry unless it's square.
Symmetry is often seen everyday by people of all ages in nature. Symmetry that we see everyday in nature is most often Bilateral Symmetry. This means that the two halves of an object are exactly mirror images of each other. Symmetry in humans the human face has a line of symmetry in some places, but some faces are more symmetrical than others. The more symmetrical your face the prettier your face will appear. A perfect example of this is supermodels and actresses. Another example of human symmetry is the kidneys, lungs, and the brain. If you draw a line or slice these organs in half, you will have a mirror image of the other. In flowers there are roughly identical petals, sepals, stamens, and leaves. While at the beach there are a wide variety of shells and underwater life with a line of symmetry, an example of this is a crab, a lobster, octopus, and starfish. Crystal G.
No more than 27.
Although some may claim it has a horizontal symmetry, closer inspection will show that the lower part is larger than the upper part and so the letter is NOT symmetrical.
Squares, circles, rectangles, and some triangles have more than 1 line of symmetry.
It is a regular pentagon!
Many shapes have more than one line of symmetry. These include a rectangle, equilateral triangle, and a square. While a rectangle has two lines of symmetry, an equilateral triangle has three.
It indicates a line such that a shape can be reflected over than line such that the image is similar to the original.
A line of symmetry is a line through a shape. It shows that on either side of this line that the picture is exactly the same. There can be more than one line of symmetry in a shape.They are 'mirror images' when a shapes are divided by a lines of symmetry.
its when you can divide a shape in half and both parts are identicalfor example.you can divide a square in more than four ways.

A parallelogram.
It will have 3 lines of symmetry if its an equilateral triangle and only 1 line of symmetry if its an isosceles triangle.
yes
A circle or sphere has an infinite number of lines of symmetry.
