Ex 1 Rewrite a Statement in if-then Form If an animal is a bird, then it has feathers. Write the if-then form, the converse, the inverse, and the contrapositive of the conditional statement "Guitar players are musicians. " Because EA and EC are opposite rays, AEB and CEB are a linear pair. Two angles are supplementary if they are a linear pair. 2-2 Analyze Conditional Statements Hubarth Geometry. Contrapositive: If you are not a musician, then you are not a guitar player. 2 2 practice conditional statements answer key strokes. To show that a conditional statement is true, you must prove that the conclusion is true every time the hypothesis is true. Statement 1 The ball is atement 2 The cat is not black. Here is an example: If it is raining, then there are clouds in the sky.

Rewrite the statements as a biconditional. This statement is false. Negation The negation of a statement is the opposite of the original statement. By definition, if the noncommon sides of adjacent angles are opposite rays, then the angles are a linear pair. Negation 1 The ball is not gation 2 The cat is black. AC BD b. AEB and CEB are a linear pair.
This statement is true because linear pairs of angles are supplementary. Conditional - true converse - false inverse - false contrapositive - true. C. EA and EB are opposite rays. You can write "lines t is perpendicular to line m" as t m. Ex 3 Use Definition Decide whether each statement about the diagram is true. So you can say the lines are perpendicular. Explain your answer using the definitions you have learned. To show that a conditional statement is false, you need to give only one counterexample. Converse: If the dog is large, then it is a Great Dane, False Inverse: If dog is not a Great Dane, then it is not large, False Contrapositive: If a dog is not large, then it is not a Great Dane, True 3.
