... AB, it follows that AP = PB = 3. Substituting and cross-multiplying, we have 6/3 = AD/PX → 6(PX) = 3(AD) → PX = ½ AD. Now let’s find an expression to represent the length of segment YR. Since segments PR and BC are parallel, we know that m∠DYR = m∠DBC. Notice also that m∠YDR = m∠BDC. Therefore, ∆YRD ...

... Explain how the criteria for triangle congruence (ASA, SAS, and SSS) follow from the definition of congruence in terms of rigid motions. Prove theorems about lines and angles. Theorems include: vertical angles are congruent; when a transversal crosses parallel lines, alternate interior angles are co ...
