Same length, same width, same size, same shape
A figure has rotational symmetry if you can turn it about a figure.
All triangles are unique compared to other polygons inasmuch that they have only 3 sides and no diagonals.
there is many ways such as using a mirror or just by looking its not hard. A triangle has 1 line of symmetry right down the biddle because when you fold it over the sides match up, its like folding paper because you can fold it portrait or landscape but you cant fold it diagonal (corner to corner)
if it has a right angle

Same length, same width, same size, same shape
If your asking what shape has three lines of symmetry, your answer would be an equilateral triangle. You can tell how many lines of symmetry a shape that has all angles of the same measure has by looking at it's angles. Ex., pentagon has five angles--five lines of symmetry; octagon has eight angles, eight lines of symmetry; etc.
i could tell by the look of her body ,that she new what symmetry was.
A figure has rotational symmetry if you can turn it about a figure.
symmetry principles always tell us something important. They often provide the most valuable clues toward deciphering the underlying principles of the cosmos, whatever those may be. In this sense, therefore, symmetry is certainly fruitful. Whether or not some all-encompassing symmetry is the grand principle that will necessitate our "theory-of-everything" is still to be determined.
ok i will tell
You turn it a quarter to see if it still has a line of symmetry.
All triangles are unique compared to other polygons inasmuch that they have only 3 sides and no diagonals.
A hexagon can have 0,1,2,3,4 or 6 (not 5) lines of symmetry.
If any one of them is longer than or equal to the sum of the other two, they can't form a triangle. If the lengths of the line segments are a, b and c, they form a triangle iff:a + b > ca + c > bb + c > a
