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.
Well since isosceles can only have two equal angles and two equal sides and a triangle has 3 angles and 3 sides it can really only have 1 line of symmetry.
It has 1 line of symmetry
One - from the vertex between the sides of equal length to the centre of the opposite side.
A regular polygon with x sides has x lines of symmetry. Each line of symmetry passes through a vertex and the midpoint of the opposite side. For example, a regular hexagon has 6 lines of symmetry, one for each pair of opposite sides. The formula for calculating the number of lines of symmetry in a regular polygon is equal to the number of sides x.
Isosceles triangle, kite. -improvement: an isosceles triangle actually has three lines of symmetry, equal to the number of sides. It is easy to design irregular polygons with an odd number of sides that have just one line of symmetry. A parabola. Many more functions that are more complex - cardioid, for example.
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.

There is only one in a trapazoid because if you look at it there is only one line that can be cut to have both sides equal
it depends upon the triangle that it have equal sides or not
They don't have a line of symmetry at all because there is no line, folded along which can both sides exactly match
Symmetry is a shape, object or drawing that on both sides are exactly the same! So a square, rectangle, circle, diamond, and more.When you draw something like a square cut it out and see how many times you can fold it. If you can fold it one time that fold represents a line of symmetry! A heart ❤️ has one line of symmetry. If you can not fold it with equal parts on both sides then it does not have a line of symmetry.
