Second application: Now that you know that $C'$ is true, combine that with the first statement and apply the contrapositive to reach your conclusion, $A'$. 1, -5)Name the ray in the PQIf the measure of angle EOF=28 and the measure of angle FOG=33, then what is the measure of angle EOG? Justify the last two steps of the proof. Your statement 5 is an application of DeMorgan's Law on Statement 4 and Statement 6 is because of the contrapositive rule.
