Joel and melinda provide the following proofs for vertical angles to be equal:
joel's proof: angle 2 + angle 3=180° (t is a straight line)
angle 1 + angle 2 = 180° (pq is a straight line)
therefore, angle 1 + angle 2 = angle 2 + angle 3 (transitive property of equality)
hence, angle 1 = angle 3 (subtraction property of equality)
melinda's proof: angle 1 + angle 2 + angle 3 + angle 4 = 360°
therefore, angle 1 + angle 4 = 180° (t is a straight line)
hence, angle 4 = angle 2 (transitive property of equality)
which statement is correct?
a joels is correct
b melindas is correct
c both melinda and joels is correct
d neither is correct
