in desperate need of help! medals rewarded! What is the converse of the statement “If two angles share a common side, then they are adjacent. A. If two angles do not share a common side, then they are not adjacent. B. If two angles are adjacent, then they share a common side. C. If two angles are not adjacent, then they do not share a common side. D. If two angles share a common side, then they are not adjacent.

lol..

The converse means you need to take the second half of the original sentence first as the "if....", then put in the first half as the new second half. Like: If it's sunny, I am happy. Converse: If I am happy, it is sunny.

OpenStudy (anonymous):

so then it would be B right?

OpenStudy (anonymous):

right :) Good work :)

OpenStudy (anonymous):

thanks:)

OpenStudy (anonymous):

btw, B is right... that is the converse, but the converse may not be actually true.

OpenStudy (anonymous):

so b isnt the answer then?

OpenStudy (anonymous):

no, sorry to be confusing. b is definitely right.

OpenStudy (anonymous):

oh lol okay hah, so basicall conver means opposite right?

OpenStudy (anonymous):

What I meant is that a converse may be a lie. If it's sunny, I am happy. If I am happy, it is sunny.... <<<---- might be false, don't you think?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Converse is the original statement, turned around.

OpenStudy (anonymous):

Here's a quick set of notes: when they say "p" and "q", it's just short for saying some phrase, like p might be "I am happy" and q might be "it is sunny" statement: if p then q converse: if q then p inverse: if not p then not q contrapositive: if not q then not p

OpenStudy (anonymous):

So, don't get confused between converse and inverse. Converse is reversing the order. Inverse means taking the original statement in the same order and changing it to say "If NOT...... then NOT...."

OpenStudy (anonymous):

so what about this one? if p--->q and q--->r are true statments, then p---> r a. true b. false it would be true right?

OpenStudy (anonymous):

This is a different type of question, but you are correct. I think it is called a law of syllogism.

OpenStudy (anonymous):

what about this? What is the conclusion of the statement “If a triangle is isosceles, then it has two congruent sides”? A. A triangle is isosceles B. It has two congruent sides C. Triangles have congruent sides D. If a triangle has two congruent sides, then it is isosceles.

OpenStudy (anonymous):

it would be A right?

OpenStudy (anonymous):

or i ment D

OpenStudy (anonymous):

No, I think it's D, but I hate the way they worded that question

OpenStudy (anonymous):

i know me to lol

OpenStudy (anonymous):

Sorry... keyboard is not cooperating... Seems like you have the idea with these problems :)

OpenStudy (anonymous):

yes one more just to make sure im clear on this What is the converse of the statement “If the light is red, then I will stop the car”? A. If the light is not red, then I will not stop the car. B. If I will not stop the car, then the light is not red. C. If the light is red, then I will not stop the car. D. If I will stop the car, then the light is red. its d right?

OpenStudy (anonymous):

Hey, I like helping but I have to apologize... gotta run. Can you repost that last question as a new question so someone else can help? :) Good luck..

OpenStudy (anonymous):

OpenStudy (anonymous):

yes, D is it... sorry, I could have done that one more :)
