The question does not make any sense.
A "midsegment" suggests the mid part (or point) of a line. But a triangle cannot have a line opposite to a line since it has only three lines!

The longest side of a triangle is opposite to its largest angle
the midsegment
The side opposite the right angle of a triangle is the hypotenuse which is the longest side
The opposite side of any angle in a triangle is the side that is not part of the angle. The side opposite the right angle is the longest side, called the hypotenuse.
A midsegment of a triangle is parallel to the side of the triangle, and it's length is half the length of that side
The length of a midsegment is half that of the parallel side of the triangle; assuming the midsegment is parallel to the [given] base, then its length is 27 ÷ 2 = 13.5 units.
It would be called the midsegment of the triangle. And when you have all the midpoints of the triangle joined, you would get the midsegment triangle. It is one fourth of the area of the actual triangle
a midsegment of a triangle
The midsegments of a triangle are the midpoints of the three sides of the triangle.

The side opposite the right angle of a triangle is the hypotenuse which is the longest side
The opposite side of any angle in a triangle is the side that is not part of the angle. The side opposite the right angle is the longest side, called the hypotenuse.
The shortest side of a triangle is opposite to the smallest interior angle.
It is opposite the right angle of the triangle.
