White up-pointing triangle
An outlined upward triangle, conventionally the inactive or unselected partner to the filled ▲ in sort controls and steppers. It is also used in mathematics for triangle notation and in change notation as a stand-in for delta, though the Greek letter Δ is the semantically correct choice there. The thin outline weakens below about 12px.
