If the angle measure is the largest of the triangle, what do you know about the side opposite?
it is the length.
if a side is the shortest of the triangle, what do you know about the angle opposite that side?
it is the degree measure.

A) the longest side

B) the smallest angle

Step-by-step explanation:

Relationship of sides to interior angles in a triangle

In a triangle:    

Recall that in a scalene triangle, all the sides have different lengths and all the interior angles have different measures. In such a triangle, the shortest side is always opposite the smallest angle. Similarly, the longest side is opposite the largest angle.

So,

A) the longest side

B) the smallest angle
