Maybe yes or no
YES!!! An equilateral triangle has three lines of symmetry. They are drawn from any one corner to the opposite base. They should all intersect at the centre of the triangle. By comparison, an Isosceles triangle has only one line of symmetry. From the one unequal angle to the opposite side. Right angled, and scalene triangles do not have lines of symmetry.
I imagine that all of them have three straight lines.
not all shapes have lines of symmetry. one example is a triangle.
All regular octagons have the same number of lines of symmetry, but octagons with unequal sides would have fewer lines of symmetry.
no they do not they have to be equal so that proves there is NO lines of symmetry * * * * * It depends on the triangle. Equilateral triangles have 3 lines of symmetry, Isosceles triangles have 1 and all other triangles have none.
A scalene triangle. Though it's usually defined as having three sides of different lengths, this is an equivalent definition: all equilateral triangles have three lines of symmetry, and all isosceles triangles have one (no triangle has two lines of symmetry).
It depends on the type of triangle: -- scalene triangles have three sides of different length, and no lines of symmetry -- isoceles triangles have one line of symmetry that includes the apex -- equilateral triangles have three lines of symmetry, all bisectors through a vertex
The Answer is 6!
Six
Maybe yes or no
no
All triangles have less than 4 lines of symmetry.
For a right isosceles triangle (45-45-90), there is one line of symmetry that bisects the hypotenuse. For all other right triangles, there are zero lines of symmetry.

All three lines of a triangle are equal.
If you're referring to an equilateral triangle, a triangle in which all three sides are the same length, then there are three lines of symmetry.
