task_geometry__regular_polygon_decomposition__perimeter_value

Contract

  1. Domain: geometry
  2. Scene id: regular_polygon_decomposition
  3. Task id: task_geometry__regular_polygon_decomposition__perimeter_value
  4. Supported query_id values: single
  5. Answer schema: integer
  6. Annotation schema: point_map
  7. Scalar annotation checked: true (not scalar-eligible; the task binds polygon center and apothem-foot roles)

Program Contract

  • solve_formula(regular_polygon_equal_wedge_decomposition, target=regular_polygon_perimeter, formula_schema=two_area_divided_by_apothem); scene=regular_polygon_decomposition; scope=perimeter_value

Reasoning Operations

Families: filtering, formula_evaluation

Query Semantics

  • single asks for regular-polygon perimeter from visible total-area and apothem labels.
  • The semantic prompt branch uses perimeter_from_total_area_and_apothem; the public query id remains single.
  • The number of polygon sides, selected side, style, font, layout jitter, and rotation are internal replay metadata.

Prompt Bundle

  • Prompt text is loaded from src/trace_tasks/resources/prompts/geometry/regular_polygon_decomposition/geometry_regular_polygon_decomposition_v1.json.
  • Prompt modes: answer_only and answer_and_annotation.

Annotation

Prompt-facing annotation uses pixel-space point map keys O and M. These mark the polygon center and the apothem foot. Measurement labels and readout panels remain visible diagram content and private verifier metadata. This task does not shade a wedge region or label side endpoints; the decomposition lines remain visible only to support the area-apothem perimeter relation.

Determinism

Generation is deterministic for a fixed seed, params, config, and prompt bundle version.
