See the diagram. Not just look at it.
the shape of this subject
Geometry rewards students who draw the figure themselves, mark what they know, and stare. Brainback nudges you toward the sketch — never toward the theorem's evaluated conclusion.
Because geometry rewards the students who do the reps — and punishes the ones who outsource them.
Add Geometry as a Learn subject and every problem in these areas routes to the Socratic tutor — attempt-first, hint-laddered, output-guarded.
Attempt → correction → guiding question. No answer. Ever. Verbatim from a beta session.
I labeled ∠BAC = 40° and ∠ABC = 60°…
Draw an auxiliary line — what would make this triangle similar to another?
no answer · one guiding question · your next move
the anti-pattern
Answer machines make geometry look like a solved problem. It isn't. The exam room reveals whose reasoning was built and whose was rented.
the recall card
Every wrong attempt and low-scored explain-back becomes a card. SM-2 schedules them — the tricky ones come back tomorrow, the solid ones drift out to next week, then next month.
Recall the core concept in your own words. Then apply it to a fresh example under 2 minutes.
The subject where the shortcut has always been most expensive.
Limits, rates, and shapes of change — earned, not delivered.
Where symbolic manipulation becomes second nature — or doesn't.
Unit circle, but also unit intuition.
Vectors are directions, not numbers.
The subject where wrong feels right — until Brainback slows you down.

Attempt-first. Never the answer. Add it as a Learn subject in 30 seconds.
