The phrase "above the angle of" is correct and usable in written English.
It can be used in contexts related to geometry, navigation, or discussions about positioning or orientation.
Example: "The bird flew above the angle of the roof, creating a striking silhouette against the sunset."
Alternatives: "over the angle of" or "atop the angle of".
The species differ only in the shape of the crest in adult males (described above), and possibly in the angle of certain skull bones.
The needle was positioned above the AN trunk with the angle of the tip adjusted towards the IAM.
At the earth's northern latitudes for much of the year, and at the midlatitudes in winter, the sun does not stay far enough above the horizon (45 degrees) for the angle of the sun's rays to guarantee an efficient ultraviolet-B bath.
A so-called internal clock mechanism in birds involves the ability to gauge the angle of the Sun above the horizon.
A plugin may then add additional meta-data for which it is responsible, e.g. the angle of the beam above the horizon.
If the angle of incidence is above the so-called critical angle (as compared to the normal of the surface), defined by Snell's Law (Katz, 2002), the light is no longer refracted but is internally reflected.
Different methods are used to determine geographic latitude, as by taking angle-sights on certain polar stars or by measuring with a sextant the angle of the noon Sun above the horizon.
Corpus callosum thickness was measured using 400x ocular magnification at the sagittal midline and above the lateral angle of the frontal horn of the lateral ventricle medial to the external capsule.
The average hydrodynamic radius (Rh) of the micelles remained almost constant above the cmc value over the angles of scattering measurement.
GISAXS measurements were performed at the SAXS beamline of the Elettra synchrotron, using monochromatic radiation with wavelength 0.154 nm, and several grazing incidence angles slightly above the critical angle of total external reflection.
