Because two points determine a line, you can draw altitudeBD⎯⎯⎯⎯ perpendicular to AC⎯⎯⎯⎯⎯ with height h. By the definition of a sine ratio,_, which can be rearranged into a sinC=h. The area of △ABC is A=1/2bh. The _ can be used to write A=1/2b(a sinC), which becomes A=1/2ab(sinC) by the _.
Choices: sin C=h/a, sin c=a/h, symmetric property of equality, transitive property of equality, substitution property of equality, associative property of equality, distributive property of equality, and commutative property of multiplication
