Identities can be visualised using models that are:
AGeometrical
BHistorical
CBiological
DElectrical
Answer & Solution
Correct answer: A. Geometrical
1. A square of side a + b can be cut into parts.
2. The areas of those parts add up to the identity.
3. So identities are visualised using geometrical models.
4. The answer is geometrical.
