It will if isosceles or equilateral.
The first will have a single line: the bases' perpendicular bisector produced through the apex.
The second will have 3 in the same way.
That depends on what type of triangle it is because an equilateral triangle has 3 lines of symmetry whereas an isosceles triangle has only 1 line of symmetry and any other triangles have no lines of symmetry.
No.
it depends on the triangle
No
First of all, your grammar is terrible. The question should be "Does a triangle have 2 lines of symmetry and 2 lines of rotational symmetry? and the answer is no. A triangle can not have 2 lines of rotational symmetry, because you only rotate the image, you do not use any lines.
An isosceles triangle has 1 line of symmetry, an equilateral triangle has 3 and a scalene triangle has no lines of symmetry.
It depends on what kind of triangle. A scalene triangle (no equal sides or angles) would not have any lines of symmetry. An isosceles triangle would have 1 line of symmetry, and an equilateral triangle would have 3 lines of symmetry.
caca
a scalene triangle has no lines of symmetry
An equilateral triangle has 3 lines of symmetry whereas an isosceles triangle has 1 line of symmetry but normally no triangles have 2 lines of symmetry.
An equilateral triangle contains at least 2 lines of symmetry (it actually contains 3 lines of symmetry). An equilateral triangle is also radially symmetric.If the question is "Is there a triangle with exactly 2 lines lines of symmetry?", the answer is no.
An equilateral triangle has 3 lines of symmetry
