There is no specific name in general. If the line segments are straight, then it is a triangle.
Triangle

scalene triangle
Every triangle has three sides. If it has any number of sides other than three, then it isn't a triangle.

scalene triangle
A triangle is usually referred to with a name consisting of the labels of its three vertices. If that's the system implied in this question, then the three vertices of the subject isosceles triangle are the points 'j', 'k', and 'l', and 'kl' is the line between the points 'k' and 'l', i.e. one side of the triangle. We don't know any more than this, like whether or not the side 'kl' is one of the two equal sides.
