Question

I need help with this chart for Geometry. I partially get it and need help. In case you can't read the writing:
Converse - If it's a polygon then it's triangle
Inverse - If it's not a triangle then it's not a polygon
Contrapositive - If it's not a polygon then it's not a triangle. Medal will be rewarded for answer being accurate and correct. See below for Attachments.

Answer 1

@satellite73

Answer 2

true / false?

Answer 3

the statement "if it is a triangle, then it is a polygon" is obviously true
the converse "if it is a polygon, then it is a triangle" is silly
it could be a square for example , or an octagon
so that one is false

Answer 4

the Inverse - If it's not a triangle then it's not a polygon is also False
the inverse is the same as the converse

Answer 5

I gave you the the part where my handwriting was hard to read. It's in the question.

Answer 6

and finally
Contrapositive - If it's not a polygon then it's not a triangle.
is the same as the original statement, so it is True

Answer 7

@satellite73 so the counterexample for converse and inverse are the same

Answer 8

@zepdrix Read @satellite73 answer's and help me to the parts that are false

Answer 9

yes

Answer 10

a square is a counter example for both
