Only an equilateral triangle has rotational symmetry.


What triangle has lines of symmetry?

An isosceles triangle has 1 line of symmetry, an equilateral triangle has 3 and a scalene triangle has no lines of symmetry.


How many limes of symmetry does a triangle have?

If it is an equilateral triangle then it has 3 lines of symmetry. If it is an isosceles triangle then it has 1 line of symmetry


Does a triangle have more than one line of symmetry?

It will have 3 lines of symmetry if its an equilateral triangle and only 1 line of symmetry if its an isosceles triangle.


Can you show me a triangle with only one line of symmetry?

An Isosceles triangle has at least one line of symmetry but if it has more than one line of symmetry it can be an Equilateral triangle as well as a Isosceles Triangle. So a triangle with one line of symmetry is always Isosceles and If it has more than one it is always an Equilateral triangle as well as an Isosceles triangle. Example of an Isosceles triangle:


Does an equilateral triangle have one line of symmetry?

yes


Has an equilateral triangle have a line of symmetry?

Yes it has three.


How can you tell whether a triangle has reflecton symmetry?

Triangle with 2 lines of symmetry?

A triangle with two lines of symmetry does not exist. It can have one line of symmetry (an isosceles triangle) or three (an equilateral triangle), but not two.


How many symmetric line has the triangle?

The number of lines of symmetry of a triangle depends on what triangle you are talking about. An equilateral triangle has three lines of symmetry (one corresponding to each altitude). An isosceles triangle (that is not equilateral) has one line of symmetry. Other triangles have none.
