Use the following image to answer the questions below: a. Based on the picture, what properties can you be sure this figure has? Think about angles, lines, and intersections.
b. Are l and m parallel? Explain your thinking.
c. What would you need to do to prove that l and m are parallel?

Step-by-step explanation:

a). From the given picture, lines 'l' and 'm' are the lines intersected by two transversal lines.

Angle formed between the line 'l' and transversal lines are 60° and 120° respectively.

b). From the given picture, we can not conclude that the lines 'l' and 'm' are the parallel lines.

c). To prove the lines 'l' and 'm' parallel, another angle at the point of intersection of lines 'm' and the transversal lines should be known.

So that we can prove the angles formed at line 'l' and line 'm' equal using "corresponding angles theorem".
