Complete the statements below. We see that 22 and 23 are corresponding angles. And since the lines u and v are parallel, 22 and 23 are congruent. So, m2 3 = 150 °. We see that 21 and 22 are Choose one Thus, 21 and 22 are Choose one So, mZ1 = 1 Therefore, 21 and 23 are Choose one We also see that 2 1 and 23 are Choose one The relationship between 2 1 and 23 is an example of the following rule. When parallel lines are cut by a transversal, Choose one
