Task formats

Exact constructed-diagram angle entry

Exact constructed-diagram angle entry asks the player to inspect a deterministic geometry construction, add only permitted auxiliary relations, and enter the exact target angle in the declared angular unit.

Practice focus

Geometry, shapes, and measurement

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 where geometric measure is derived from a visible exact construction or decomposition
