Mandibular Gonial Angle Measurement Tool
Mandibular Gonial actual ordered planar-ray angle from independently identified measurement landmarks;3 Dprojection, protocol and biological interpretation caller established. Caller independently establishes sample/context/calibration applicability; not definitive chronology, provenance, taxonomy, disease or human identity.
Description
A gonial-angle measurement depends on independently defined rays and a measurement plane.
A gonial-angle measurement depends on independently defined rays and a measurement plane.1
A planar angle alone does not diagnose age, sex or health. Use Mandibular Gonial Angle Measurement Tool to evaluate the supplied inputs under the model explained below.
When to use Mandibular Gonial Angle Measurement Tool
Use Mandibular Gonial Angle Measurement Tool to evaluate the supplied inputs under the model explained below. Establish the units, measurement scope and model assumptions before entering values.
How to use Mandibular Gonial Angle Measurement Tool and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Observed mandibular gonial ray one, Observed mandibular gonial ray two using the field table and validation rules below, then run the tool.
- Read Observed planar angle degrees; interpret the units, signs, ordering and unknown-value placeholders described below.
- Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedMandibularGonialRayOne | Observed mandibular gonial ray one | array of number | Required; constraints below |
| observedMandibularGonialRayTwo | Observed mandibular gonial ray two | array of number | Required; constraints below |
Enter exactly two finite components for each of two nonzero planar ray vectors. Normalize by their lengths, clamp their dot product into [−1,1] and return acos in degrees from 0 to 180. No landmark selection, image calibration or biological classification occurs.
angleDegrees=acos(clamp(dot(unitRay1,unitRay2),−1,1))×180/π Use the field order, units and branch conditions described above.
| Output field | Meaning | Value type |
|---|---|---|
| observedPlanarAngleDegrees | Observed planar angle degrees | number |

}Limitations and assumptions
A planar angle alone does not diagnose age, sex or health. Apply the exact scope and assumptions explained above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
