We see that 1 and 22 are Choose one Thus, 21 and 22 are Choose one
So, m 2 2 = 0
w
We see that 22 and 23 are Choose one
And since the lines g and h are parallel, 22 and 23 are Choose one
So, m 23 =
Therefore, 21 and 23 are Choose one
v
We also see that 21 and 23 are Choose one
v
The relationship between 21 and 23 is an example of the following rule.
When parallel lines are cut by a transversal, Choose one
