No, scalene triangles, which have sides of different lengths, have none. Isosceles triangles, with only two sides the same, only have one.
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).

Oh, dude, that's an easy one. A triangle has three lines of symmetry. Yeah, like, you can fold that bad boy in half three different ways and it's still looking symmetrical. Triangles, man, they're like the cool kids of geometry.
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.
Of the the seven letters, ABCDEFG, F and G have no lines of symmetry. However,Êall of them could have lines of symmetry if theyÊwere presented in three dimensions.
no, only equilateral triangles have 3 lines of symmetry
Different triangles may have none, one, or three 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
because there are only THREE sides/ray.

A right triangle doesn't necessarily have any lines of symmetry. But if it has, it can't have more than one.
No such thing as a regular triangle. You need to be more accurate in your triangular description. Equilateral triangle is symmetric about three lines of symmetry. Isosceles triangle is symmetric one line of symmetry. Right-angled, and Scalene triangles have no lines of symmetry.
The Answer is 6!

Most triangles don't have any lines of symmetry. An isosceles triangle has one. An equilateral triangle has three.
Yes, both triangles and squares have lines of symmetry and rotational symmetry. An equilateral triangle has three lines of symmetry and a rotational symmetry of order 3, meaning it can be rotated by 120 degrees and still look the same. A square has four lines of symmetry and a rotational symmetry of order 4, allowing it to be rotated by 90 degrees and still appear unchanged. Other types of triangles and quadrilaterals may have different numbers of symmetries based on their specific shapes.
An equilateral triangle has exactly three lines of symmetry. It is the only shape that contains exactly three lines of symmetry.
