Best Answer

Yes, every isosceles triangle has at least one line of symmetry, usually drawn down the middle from the top point, down in the middle of the triangle's base.

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:

this shape has at least one line of symmetry The answer is:- Symmetrical.

An isosceles triangle

It depends on the definition used. If you are defining an isosceles triangle as having exactly two sides of equal length, then no. If you define it as having at least two, then yes. An equilateral triangle has three lines of symmetry, but whether or not that counts as an isosceles triangle depends on the definition used. So, maybe.

For example an isosceles triangle has only one line of symmetry
