Which conditional has the same truth vaule as its converse?
if x = 7, then IxI = 7
if a figure is a square, then it has four sides
if x - 17 = 4, then x = 21
if an angle has a meausre of 80 degrees then it is acute

Question

Which conditional has the same truth vaule as its converse?
if x = 7, then IxI = 7
if a figure is a square, then it has four sides
if x - 17 = 4, then x = 21
if an angle has a meausre of 80 degrees then it is acute

Do you know what the definition of converse is?

anonymous · Answer

Converse means the "if" and "then" parts of a sentence are switched. For example, "If two numbers are both even, then their sum is even" is a true statement. The converse would be "If the sum of two numbers is even, then the numbers are even," which is not a true statement.

im still confusedd.

anonymous · Answer

Right. So, rewrite all of those statements as their converse:

If |x| = 7, then x = 7
If a figure has 4 sides, then it is a square
If x = 21, then x - 17 = 4 
If an angle is acute, its measure is 80 degrees.

Which of those is true?

its be the second one/

anonymous · Answer

A rectangle has 4 sides. So, that's not quite right.

Another way to approach it is to try and think of a counterexample for each of the statements, then see which one you have left that doesn't have a counterexample.

anonymous · Answer

okay so then it would be the third one becuase they are different.

anonymous · Answer

That's correct, but I'm not sure I understand your reasoning.
