For Q7, I disagree. Vertical angles share only the intersection. I don't have the diagram, but I can't see how CED and BED can be vertical angles, since D is on both of them.
Q9 looks like a better possibility.
A city planning engineer in Cleveland must check the 10 angles that make up the three intersections on the map of downtown. If any of the angles formed by the intersections of the streets is greater than 135°, different road signs have to be used due to a new rule created by city council. She knows CED = 52 degrees and that FJG = 64 degrees, so she knows she will NOT need a protractor to measure the unknown angles.
Q7: Which angle is vertical to CED?
A: AEC
B: AEB
C: BED (my answer)
D: AED
Q8: What is the measure of the angle in your #7 answer? (short answer, my answer was 52 degrees)
Q9: Which angle is vertical to FJG?
A: FJH
B: GJI
C: HJI (my answer)
D: FJI
Q10: What is the measure of the angle in your #9 answer? (short answer, my answer was 64 degrees)
I don't have a problem with geometry, I really don't. For some reason, the new Common Core testing system doesn't line up with the lessons I am currently learning online. I would like the answers, but more than anything, just explain to me how to find the vertical angles and use them to find the measure of the angle!
Also for some reason I can't post a picture, I'll try and find a way to do it
