Final answer:
To prove that angle 1 is approximately equal to angle 2, we can use the fact that corresponding angles of parallel lines are equal.
Step-by-step explanation:
To prove that angle 1 is approximately equal to angle 2, we need to show that they have the same measure. Given the information provided, it is important to note that parallel lines have corresponding angles that are equal. In this case, we can consider angle 1 and angle 2 as corresponding angles because they are situated in the same position relative to the parallel lines. Therefore, we can conclude that angle 1 is approximately equal to angle 2.
