MATH 01310 · 4 cr · Advanced (300+)
College Geometry
Advanced credit + direct Praxis Geometry + what you will teach in HS geometry.
Suggested prep window: 3–5 weeks (proof habits take time)
Prerequisites to lock first
- Euclidean HS geometry
- Comfort writing short proofs (Discrete Structures helps)
A-grade strategy
- Write proofs every day — even 15 minutes — more than watching videos.
- Keep a criterion sheet: SSS/SAS/ASA/AAS, AA~, parallel-line theorems.
- Redraw every diagram and mark givens before proving.
