Ordinarily yes. This is called "contraposition" in formal logic :
For any statement where A implies B, then not B always implies not A. Proving or disproving either one of these statements automatically proves or disproves the other.
If A then B means that B is a subset of A, and anything not part of B cannot be part of A.
However, some if-then or cause-effect statements, once made negative or reversed, represent an entirely different fact that may or may not be true.
For example:
"If I get the high score, then I will receive the award."
would be true in contraposition if the award is based only on the score.
"If I do not receive the award, then I did not get the high score."
However, if the award was denied on some other basis, the contraposition is not valid.
The valid statement would be "If I get the high score, then I will definitely get the award."
"if" clause and a "then" clause. The "if" clause states a condition that must be true in order for the statement to be true, and the "then" clause states the result or outcome if the condition is met.
A clause is a sort of sentence within a sentence. In some cases they can be joined together with conjunctions such as or, and or but. For example: He put on his coat and they walked to the beach. "He put on his coat" is one clause and "They walked to the beach" is another. Because they do not depend on one another and are joined by a coordinating conjunction (the word and) such clauses are referred to as coordinate clauses.
The temperature falls fast when the sun sets. When the sun sets is an adverb clause. Adverb clauses are introduced by subordinating conjunctions. Although,after, because, when, etc.
An independent clause (or main clause) can be defined as a clause that can stand by itself, also known as a simple sentence. An independent clause contains a subject and a predicate ; it makes sense by itself. Independent clauses can be joined by using a semicolon or a coordinating conjunction such as for, and, nor, but, or, yet, so.
The noun clause is that Stella took dance lessons at her age. The noun clause is introduced by a relative pronoun that and acts as the object of the verb believe.A noun clause is dependent clause which can be used as a noun as the subject of a sentence or the object of a verb or a preposition. The noun clauses are generally introduced by relative pronouns such as that, which, who, when, whichever, whoever, whenever, whether and so on.
true
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.
One false statement about subordinate clauses is that they always function as independent sentences on their own. Another false statement is that they are always placed at the beginning of a sentence. Subordinate clauses can also come after the main clause in a sentence.
An SQL statement is a complete set of clauses which returns a value and ends with a semicolon(;) A statement is made up of several clauses Ex: select * from person where f_name='me'; In this ex ' select * from person where f_name='me';' is the statement and select*, from person, where f_name= are the clauses
When an exception is thrown within the body of a try statement, the catch clauses of the try statement are examined in the order in which they appear. The first catch clause that is capable of handling the exception that was thrown, is executed. The remaining catch clauses are ignored
False

Dependent (subordinate) clauses are clauses that have a subject and a verb but cannot stand alone.An example is:When the cat ran under the car.This is a dependent clause because the word "when" makes the statement unable to stand on its own.

Subordinate clauses are clauses that cannot stand alone because it does not express a complete thought. Examples of a subordinate clause include, "Until she had her cup of coffee" and "Since that fateful day in January".
Commas are used differently when a clause is an independent clauses or if the clause is a dependent/subordinate clauses.
