If the measure of two angles have a sum of 180 degrees then the angles are supplementary. M<A+m<B= 180 degrees. <A and <B are supplementary. I need to figure out if this is valid or invalid. A Valid, Law of Syllogism B Valid, Law of Detachment C Valid, but it doesn’t use either law D Invalid I don't just want the answer,I want to figure out how to get the answer. I have three more others like this so learning how this works would really help me with the others.

    From Geometry, we know that if the sum of the measures of 2 angles (A and B) is 180, then <A and <B are supplementary. Law of Detachment says in p implies q, if p is true, then q is true..since you are given that m<A+m<B=180 as p then A and B as supplementary (as q) must be true.

    Well I know it's Valid, but I'm not sure which law I would've used to figure out that it was valid.

    What's the best way of figuring out which law it is and the meanings of those laws? Also, could you help me with the other three?

    it states that in a conditional statement, if the premise is true,then the conclusion is true..and since you are given a true premise then the conclusion must be true...law of detachment...to say it in short..law of detachment involves one conditional statement.while law of syllogism involves two

    So it's like Law of Detachment If it rains, I will stay inside. It is raining, Then I will stay inside. Law of Syllogism If it rains, I will stay inside. If I stay inside, I will play Monopoly. If it rains, I will play Monopoly. Is that right?
