It has 1 line of symmetry
one
If it is an equilateral triangle then it has 3 lines of symmetry. If it is an isosceles triangle then it has 1 line of symmetry
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.
An isosceles triangle has rotational symmetry of order 1.
An isosceles triangle has 3 sides and 2 of its sides are equal in lengths
one
An isosceles triangle has only 1 line of symmetry.
4 sides, each of which is a isosceles triangle with 3 lines of symmetry, gives 12.
An isosceles triangle has 1 line of symmetry
an isosceles has only 1 line of symmetry
If it is an equilateral triangle then it has 3 lines of symmetry. If it is an isosceles triangle then it has 1 line of symmetry

An isosceles triangle has rotational symmetry of order 1.
An isosceles triangle has 3 sides and 2 of its sides are equal in lengths
An isosceles triangle has only one line of symmetry
An isosceles triangle definitely has three axes of symmetry
It depends on the type of triangle. A scalene triangle (no equal sides) has no rotational symmetry. An isosceles triangle (2 equal sides) has rotational symmetry order 2. An equilateral triangle (3 equal sides) has rotational symmetry order 3. The order of rotational symmetry is how many time a shape will fit over itself during one complete rotation.
