the first is "all statement" and the second is " existential
statement"
True or false In the body of an indirect proof you must show that the assumption leads to a contradiction
True
It is true that the body of an indirect proof you must show that the assumption leads to a contradiction. In math a proof is a deductive argument for a mathematical statement.
What is the purpose of keeping a running list of new vocabulary words

What is the converse of the statement If it is snowing then it is your birthday
The converse of the statement 'If it is snowing, then it is your
birthday is 'If it is my birthday, then it is snowing.'
Is it true that if you took an if-then statement inserted a not in each clause and reversed the clauses the new statement would also be true
If the conditional (if, then) is true, then the contrapositive (reversed; if not, then not) will be also true. And vice versa, if the conditional is false, its contrapositive will be also false. for example,
If a graph passes the vertical line test, then it is a graph of a function. (True)
If a graph is not a graph of a function, then it will not pass the vertical line test. (True)
Yes, but only if the original if-then was true.
