I have a geometry question. I understand the question and its possible answers, but the answer isn't clear enough that I understand what it is asking. Can someone please help me and look at the question?

Best ResponseYou've already chosen the best response.1Do you know the name given to a pair of angles like angles 4 and 6 with regard to parallel lines? For example, are they corresponding angles?

Best ResponseYou've already chosen the best response.0I chose "sometimes" for this question, as I thought this was a very general question; not enough evidence was provided for me to fully understand the question. I'm not sure if what I chose was correct, though.

Best ResponseYou've already chosen the best response.1Could angles 4 and 6 both be equal to 40 degrees? That is, is it possible? All we know about them is that they are congruent.

Best ResponseYou've already chosen the best response.0I don't think so, there are no tick marks, so I can't be sure, but I assume that they both are 90 degrees.

Best ResponseYou've already chosen the best response.0And they are too close to being perpendicular to being 40 degrees.

Best ResponseYou've already chosen the best response.1It is not correct to assume that the angles have measure 90 each just because they look like right angles.

Best ResponseYou've already chosen the best response.1If we knew that the lines were parallel, then angles 4 and 6 would each be 90. But we do not know that the lines are parallel.

Best ResponseYou've already chosen the best response.0In order to find the answer, do we have to use proof (as in proving with reasons and statements), or just pick 1 of the 3 answers provided based on evidence?

Best ResponseYou've already chosen the best response.1For all we know, angles 4 and 6 could each be 40 degrees in which case the lines would not be parallel because same side interior angles of parallel lines are supplementary (sum to 180).

Best ResponseYou've already chosen the best response.1No need for a proof. If you think the answer is "sometimes," then show two values for 4 and 6 that make the lines parallel. Then, show 2 values for angles 4 and 6 that would not make the lines parallel.

Best ResponseYou've already chosen the best response.1>And they are too close to being perpendicular to being 40 degrees. You can't judge angle size from the diagram.

Best ResponseYou've already chosen the best response.1If angles 4 and 6 are each 40 degrees, then they are congruent. But, they do not sum to 180, so that is a time when the lines would not be parallel.

Best ResponseYou've already chosen the best response.0The main reason why I assumed they were right angles were because they are sameside interior angles, and supplementary.

Best ResponseYou've already chosen the best response.1But, angles 4 and 6 could each be 90 degrees because that makes them congruent. 90 + 90 = 180. The same side interior angles are then supplementary. The two lines are parallel.

Best ResponseYou've already chosen the best response.1So, there is a case in which the lines are not parallel (each angle 40) and then there is a case in which the lines are parallel (each angle 90). The result is sometimes as you guessed.

Best ResponseYou've already chosen the best response.1>>The main reason why I assumed they were right angles were because they are sameside interior angles, and supplementary. You do not know that the two angles are supplementary unless you are given that the lines are parallel. You were not given that the lines are parallel. Looking at a geometry diagram and making conclusions about size is dangerous. An angle is right only if it is given to be right.

Best ResponseYou've already chosen the best response.0This also helped me with another one of my problems similar to this, so I now know what the correct answer is, using what we discussed. (These questions confuse me because they are not very specific about whether it is in general, or about the graph provided.) So, thank you so much for being patient and explaining things to me!

Best ResponseYou've already chosen the best response.1You are welcome. If you want to do so, post the next problem in a new thread and post what you got for the answer, and we can compare answers. Okay?
