an isosceles has only 1 line of symmetry
Normally none but if it's an isosceles trapezoid it has one

one. It is a vertical line of symmetry which splits the A in half.
It has two lines of symmetry, one each perpendicular to each other passing thru the center of the rectangle

I assume:symmetrys = symmetriesdose = doesisoscelese = isoscelestraingle = triangleAn isosceles triangle has rotational symmetry of order 1.
A regular polygon with 22 sides has 22 lines of symmetry. Each line of symmetry passes through one vertex and the midpoint of the opposite side, or it can pass through the midpoints of two opposite sides. This property holds for all regular polygons, where the number of lines of symmetry is equal to the number of sides.
A triangle with congruent sides and angles is called an equilateral triangle. An equilateral triangle has three lines of symmetry, each one passing through a vertex and the midpoint of the opposite side. These lines divide the triangle into two equal halves, reflecting its symmetrical properties.
