For questions 9-12, consider quadrilateral ASOP. - Note that it can be proven that AAFP = AAFS by the hypotenuse-leg theorem for triangle congruence. - Since corresponding parts of congruent triangles are congruent, PF = FS. 9) Explain why AF = OF. 10) Why is ASOP a parallelogram? 11) Why is ASOP a rhombus? 2) *Let mLSOP = 74°, mLPAF = 2j +k, and mzSFO = 5j + k. Solve for the values of j and k. Questions 8 & 12, the expressions represent the measures of the stated angles to the nearest degree.
