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:
A line of reflection and a line of symmetry both show the reverse of an image.
Has nine sides
It has 3 lines of symmetry which are the perpendiculars taken from each vertex to the opposite base

A line of symmetry is an imaginary line that divides a shape into two identical halves that are mirror images of each other. For example, in a rectangle, the vertical line drawn through the center creates two equal parts, while in a circle, any line through the center is a line of symmetry. Shapes can have multiple lines of symmetry; for instance, a square has four lines of symmetry.
the only way for a right triangle to have a line of symmetry, is if the legs of the triangle are congruent. Or you can show that both non-right angles are congruent (45 degrees). you may also prove that the altitude of the triangle bisects the hypotenuse or that it equals 1/2 of the hypotenuse.
An equilateral triangle has 3 lines of symmetry
An equilateral triangle.
A line of reflection and a line of symmetry both show the reverse of an image.
It is not possible to show anything using this browser, but the only line of symmetry is the bisector of the angle.
A shape does NOT need to have line symmetry in order to have rotational symmetry.For example, the letters N, Z and S can be rotated 180° to show symmetry, but none of these show line symmetry.When the folded part Line of Symmetry. Here I have folded a rectangle one way, and it didn't work.

A nonrectangular parallelogram has rotational symmetry, but not line symmetry. Additionally, shapes such as the letters S, N, and Z can be rotated to show rotational symmetry, although they do not have line symmetry.
