An equilateral triangle has three lines of symmetry.
None.
The number of lines of symmetry of a triangle depends upon the kind of triangle it is:A scalene triangle with no side lengths equal has no lines of symmetry;An isosceles triangle with two sides equal has 1 line of symmetry that bisects the angle between the two equal sides;An equilateral triangle with all three sides equal has three lines of symmetry - the three lines are the bisectors of the three angles.A right triangle is a triangle where one angle is 90°. A right triangle is either a scalene triangle with no lines of symmetry or an isosceles triangle (where the legs are of equal length) with one line of symmetry which bisects the 90° angle.No triangle can have exactly 2 lines of symmetry.
3 lines * * * * * None if it is acute angled scalene One if it is acute angled isosceles and Three if it is equilateral.

It has 3 lines of symmetry
An equilateral triangle has 3 lines of symmetry whereas an isosceles triangle only has 1 line of symmetry and other triangles have no lines of symmetry.
An isosceles triangle has 1 line of symmetry
For a right isosceles triangle (45-45-90), there is one line of symmetry that bisects the hypotenuse. For all other right triangles, there are zero lines of symmetry.
Any isosceles triangle that is not also equilateral has exactly one line of symmetry.
one Actually, none, one or three.

A triangular based pyramid has no lines of symmetry. However, if each of the non-base triangular sides are equal it will have 3 planes of symmetry. If the base triangle is also equal, it will have 6 planes of symmetry.
