Question

The flowchart shown below shows the sequence of steps to prove the theorem, “Opposite angles of a parallelogram are equal.”

Which option best represents x and y?

x should be “Angle 5 is equal to angle 6” and y should be “supplementary angles”

x should be Angle 5 is equal to angle 6 and y should be “opposite angles of a parallelogram are equal”

x should be “SQ = SQ” and y should be “transitive property”

x should be “SQ = SQ” and y should be “reflexive property”
