straight, curved, zigzag, and bent.
Maybe they are bisector, median, altitude and the middle perpendicular. (I hope I put it in English right :)
A triangle has 3 lines of symmetry.
a equilatral triangle has at least up to 4 lines of symetry
A triangle has 3 sides and if two sides are equal then it's an isosceles triangle with one line if symmetry but if all sides are equal then it's an equilateral with three lines of symmetry.
The maximum number of triangles that can be formed by 4 lines depends on how the lines intersect. If no two lines are parallel and no three lines meet at a single point, the maximum number of triangles formed is 4. This occurs because each set of 3 lines can define a unique triangle, and with 4 lines, you can choose 3 out of those 4 in (\binom{4}{3} = 4) ways.

How many lines of symmetry does an equilateral triangle have?
a equilatral triangle has at least up to 4 lines of symetry
scalene
triangle rectangle and cube
It depends what type of triange it is. If it is an equilateral triangle, you can draw 3 lines of symmetry If it is an isosceles triangle, you can draw 1 line of symmetry If it is a scalene triangle, you cannot draw any lines of symmetry
4 sides, each of which is a isosceles triangle with 3 lines of symmetry, gives 12.

No. A triangle has 3 sides, and a parallelogram has 4 sides. No kind of triangle can be a parallelogram, and no kind of parallelogram can be a triangle. The question is a lot like asking: Can this particular model of Toyota be a Ford ?
A triangular based pyramid has no parallel lines but it does have 4 faces, 6 edges and 4 vertices.
