subtend

Stretch opposite to

Subtend is a geometry term meaning to be opposite to and delimit.

A chord subtends an arc; an angle subtends the side opposite it in a triangle.

The word extends to any situation where something stretches beneath or underlies something else: The ligament subtends the joint.

In botany, a bract subtends a flower when it grows just below it.
