an isosceles has only 1 line of symmetry
It has one line of symmetry
One.
4 sides, each of which is a isosceles triangle with 3 lines of symmetry, gives 12.
Any isosceles triangle that is not also equilateral has exactly one line of symmetry.
A trapezium can have either 0 or 1 line of symmetry, depending on its specific shape. If the trapezium is a parallelogram, it will have one line of symmetry, which is the line that divides the shape into two equal halves. However, if the trapezium is not a parallelogram, it will have no lines of symmetry, as there is no way to divide it into two equal halves through a single line.
None, normally. One if it is an isosceles trapezium.
It has 1 vertical line of symmetry
Usually none. But one in an isosceles trapezium.
A trapezium can have at most 1 line of symmetry.
One.
None.
An isosceles triangle has 1 line of symmetry
A closed wiggly line. or many irregular polygons such as scalene triangle, ordinary quadrilateral, trapezium (if not isosceles), etc.
An isosceles triangle has only 1 line of symmetry.
