The phrase "apex of the angle" is correct and usable in written English.
It can be used in mathematical or geometric contexts to refer to the vertex point where two lines or sides meet to form an angle.
Example: "To find the area of the triangle, we need to identify the apex of the angle formed by the two sides."
Alternatives: "vertex of the angle" or "tip of the angle".
Using trigonometry, the distance between two lines enclosing an angle increases as you move away from the apex of that angle.
In index-unmatched coupling of light, there is a limit on ranges of both the available beam position (measured as the distance from corneal apex) and the angle of incidence, α, as illustrated in Fig. 4. For a given beam position, there is a limited range of incident angles for which the full width of the beam can be coupled back out of the anterior chamber.
To bring cells into the standard vertical alignment, the position of the apex of the tip and the angle of the local hyphal axis at the tip were determined visually using ImageJ.
The dorsoradial artery emerges vertically from the apex of the first intermetacarpal space, crosses the angle between the extensor pollicis longus tendon lateraly and the extensor carpi radialis longus tendon medialy and turns proximaly towards the distal radio-ulnar joint.
Thus, the drop remains on the apex of the protrusions with a high contact angle and a low contact angle hysteresis, while the surface features demonstrate good mechanical resistance against capillary forces.
Our results indicate that there is a relationship between the thickness of the mandibular symphysis at the apex of the lower incisor and mandibular plane angle.
The mandibular condyles are positioned well below the apex of the coronoid process, and the gonial angle of the mandible is compressed and square in outline (viewed laterally; Figure 1A).
The first field of view was taken with the left edge of the field of view in line with the apex of the cingulum and at a right angle to the fibres of the corpus callosum and positioned so that cerebral cortical laminas II/III-V/VI were photographed.
This ventral inflection produces a distinct oblique ventral angle between the distal apex of the pubis and the middle portion of the pubic shaft, and also creates a low, triangular crest on the dorsal margin of the pubic shaft.
The deadbeat controller of the angle of attack is designed to track the regulated apex height and velocity.
