we can find symmetary in our daily life in designs of a fashion designer or a normal tailor when he stitches our dresses
Oh heavens no. A QUADrilateral means that it has 4 sides and the definition of a triangle is three sides. An isosceles triangle is specifically a triangle with two sides of the same length and one with a different length. You may be confused and wondering if a triangle is a polygon and yes, they are. A polygon is any shape with straight lines that don't intersect.
A shape with 4 straight lines in which there are 2 parallel and 2 unparallel lines is called a Trapezium.
2 lines that do not and will not intersect are called parallel lines.
2 lines of symmetry
Any 2 lines can intersect providing that they are not parallel lines
2 Lines in the same plane that do not meet are parallel. If 2 lines are in different planes and do not meet, then they are called skew lines.
2 Lines.
A rectangle.

First of all, your grammar is terrible. The question should be "Does a triangle have 2 lines of symmetry and 2 lines of rotational symmetry? and the answer is no. A triangle can not have 2 lines of rotational symmetry, because you only rotate the image, you do not use any lines.
