Two parallel lines, m and n, are cut by the transversal f as shown. Suppose m ∠Z2 = 113.
Complete the statements below:
We see that ∠l and ∠3 are (Choose one). And since the lines m and n are parallel, ∠2 and ∠3 are (Choose one). So, m∠3.
We see that ∠l and ∠2 are (Choose one). Thus, ∠l and ∠Z are (Choose one). So, m∠l.
Therefore, ∠l and ∠3 are (Choose one). We also see that ∠l and ∠3 are (Choose one).
The relationship between ∠l and ∠3 is an example of the following rule: When parallel lines are cut by a transversal, (Choose one).
