Watch: Inspect a deterministic geometry construction, add only permitted auxiliary relations, and enter the exact target angle in the declared angular unit. The shell keeps the complete question visible, reserves the canonical reply band, and reveals proof on the same task objects.

Misread: Child action: Inspect a deterministic geometry construction, add only permitted auxiliary relations, and enter the exact target angle in the declared angular unit.

Curriculum: Mapped to Angle Types.

Selection

Fresh independent work can move toward Core, Transfer, or Challenge routes; help use or confusion keeps support visible.

Help

Hints keep attention on the visible structure; reveals show the path without counting as independent evidence.

Presentation

Presentation can reduce reading and interaction load without changing the selected skill. Practice focus can bias compatible work without breaking prerequisites or story fit.

Story fit

Episodes whose mathematical action is read a code-owned geometric construction and derive an exact angle from invariant shape properties.
