3 resourcesMatrix Families
Each group is one 2×2 matrix A together with matrices built from it: Aᵀ, A⁻¹, A², 2A, −A, A ± I, and on Hard AᵀA and det A.
🧩 ConnectionsMatrix Properties
2×2 (and on Hard, 3×3) matrices grouped by what they are: a given determinant, singular, rotation, reflection, enlargement, stretch, shear, symmetric or self-inverse.
