    Transversal Challenge problem

    https://docs.google.com/drawings/u/1...454&rev=3&ac=1

    Hey, so I have the above problem and I am at a loss of how to finish solving the problem. I am supposed to identify all the values of the numbered angles but I am stuck.

    I know angle 1, 4, & 5 are all 60deg using the vertical angle theorem and alternate interior angles, but after that I am stuck.

    I know angle 2 & 3 add together to be 120deg. can it be assumed that it is split evenly?

    Can someone give me some advice as how to keep moving forward because I am stuck. Thanks.

    Unless there is additional information given, it is impossible to determine angles 2, 3, 6, 7, 8. You can't just assume 2 and 3 are equal unless you are told, say, that line d bisects the angle. As it is, there is nothing to determine the direction of line d.

    Can you quote the exact wording of the problem?

    Thank you, I will reach out to my teacher. The only directions were "Find the values of the labeled angles."
