Stage 1 of GEOMGBITS: seven trials in the angle laws — the facts that hand you an answer before any calculating starts. Straight lines, full turns, crossings, parallels, and triangles. Every figure comes with the leverage point that makes it quick.
Each trial is locked until you clear the one before it. Every level scores out of 1000 — 600 for accuracy, 400 for speed — so speed alone can't clear the bar; you have to solve most problems, and quickly. Reach 650 to unlock the next.
You can read a figure and name the law that settles it — 180° on a line and in a triangle, 360° around a point, and the angles that copy themselves across crossings, parallels, and exteriors. Leverage, not measurement.
