Here's another triangle: So, the hypothesis, or first part, of our converse is true. the converse of a conditional statement "p implies q" is given by "q implies p". Solution. Write the converse, inverse, and contrapositive statement for the following conditional statement. Does it have three sides? Statement If two angles are congruent, then they have the same measure. If we think of our original statement as 'if p, then q,' then the converse is 'if q, then p.' With our example, is the converse true? A conditional statement (or 'if-then' statement) is a statement with a hypothesis followed. Write the converse, inverse, and contrapositive statements and verify their truthfulness. Converse.Switching the hypothesis and conclusion of a conditional statement. -Inverse of conditional statement. (If q then p), Inverse statement is "If you do not win the race then you will not get a prize." Write the converse of the statement, "If something is a watermelon, then it has seeds."

For example, in geometry , "If a closed shape has four sides then it is a square" is a conditional statement, The truthfulness of a converse statement depends on the truth of hypotheses of the conditional statement. Proof: Construct another triangle, EGF, such as AC = EG = b and BC = FG = a. Write the converse, inverse, and contrapositive statement of the following conditional statement. A statement obtained by exchanging the hypothesis and conclusion of an inverse statement. Given a conditional statement, the student will write its converse, inverse, and contrapositive.
