If a and b are parallel lines, and m∠3 = 128°, what is the measure of ∠8?
Three lines are shown forming 8 angles.
If a and b are parallel lines, then corresponding angles formed by a transversal are congruent. Therefore, ∠3 is congruent to ∠8.
Given that m∠3 = 128°, we can conclude that m∠8 is also equal to 128°.
