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

What type of triangle has no lines of symmetry?
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).
How many right triangles can be formed by drawing all three lines of symmetry in an equilateral triangle?
Six
Show three lines of symmetry?
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.
Which of these letters have no lines of symmetry ABCDEFG?
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.
How many lines of symmetry does a regular triangle have?
A regular triangle (aka equilateral triangle) has three lines of symmetry - these are its medians, In general, a regular n-gon has n lines of symmetry.
Do all triangles have three lines of symmetry?
no, only equilateral triangles have 3 lines of symmetry
How many lines of symmetry does a traingle?
Different triangles may have none, one, or three lines of symmetry.
Does a triangle have a line 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
What type of triangle has no lines of symmetry?

Why can triangles not have 2 lines of symmetry?
because there are only THREE sides/ray.
Does right triangles have three lines of symmetry?
A right triangle doesn't necessarily have any lines of symmetry. But if it has, it can't have more than one.
Is a regular triangle symmetrical?
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.
How many right triangles can be formed by all three lines of symmetry in an equilateral triangle?
The Answer is 6!
How many right triangles can be formed by drawing all three lines of symmetry in an equilateral triangle?
Six
Does a triangle have 3 lines of symertry?
Most triangles don't have any lines of symmetry. An isosceles triangle has one. An equilateral triangle has three.
What figure has exactly three lines of symmetry?
An equilateral triangle has exactly three lines of symmetry. It is the only shape that contains exactly three lines of symmetry.
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.
