Answer with explanation:
A triangle is said to be scalene , if it has all three sides of unequal length.
And median of a triangle is that line segment falling from any of three vertices of triangle, divides the side on which it is falling which is opposite to angle from which it is drawn, into two equal parts.
But the median segment Does not divide the Scalene triangle into congruent Parts.
→→A scalene triangle having three Unequal sides has No symmetry with respect to a line containing a median of the triangle.
