Test 1: Axioms of Similarity
Check your basics: Proving triangles are similar using AA and SAS criteria.
Test 2: Proportionality Theorem
Numerical Application: Solving for segment lengths using BPT and similar triangle ratios.
Test 3: Area Theorem Proofs
Deep dive testing: Master the property $\frac{\text{Area}_1}{\text{Area}_2} = (\frac{s_1}{s_2})^2$ in complex figures.
Test 4: Maps & Models
Challenge your knowledge: Solving for real-world area and volume given a representative fraction (R.F.).
