Exploring Conditional Statements in Geometry

This video tutorial by Lindsay Bowden covers conditional statements, including their structure with hypothesis and conclusion, and the use of 'if, then' phrases. It explains the converse, inverse, and contrapositive forms of conditional statements with examples. The video also introduces biconditional statements, which use 'if and only if' phrases, and provides exercises to practice these concepts.

What are the two main components of a conditional statement?

• Hypothesis and Conclusion

• Premise and Result

• Subject and Predicate

• Cause and Effect

What does the converse of a conditional statement do?

• Negates the hypothesis and conclusion

• Switches the hypothesis and conclusion

• Keeps the hypothesis and conclusion the same

• Adds a new hypothesis

How is the inverse of a conditional statement formed?

• By adding a new hypothesis

• By keeping the hypothesis and conclusion the same

• By switching the hypothesis and conclusion

• By negating the hypothesis and conclusion

What is the contrapositive of the statement 'If I eat a whole pizza, then I will be full'?

• If I eat a whole pizza, then I will not be full

• If I am not full, then I have not eaten a whole pizza

• If I do not eat a whole pizza, then I will not be full

• If I am full, then I have eaten a whole pizza

What is the converse of the statement 'If a number is even, then it is evenly divisible by two'?

• If a number is evenly divisible by two, then it is even

• If a number is not even, then it is not evenly divisible by two

• If a number is even, then it is not evenly divisible by two

• If a number is not evenly divisible by two, then it is not even

What phrase is used in a biconditional statement?

• If and only if

• If then

• If not

• Only if

When is a biconditional statement true?

• When the conditional statement is true

• When the converse is true

• When both the conditional statement and the converse are true

• When neither the conditional statement nor the converse is true

Rewrite the statement 'All quadrilaterals have four sides' as a biconditional statement.

• A shape has four sides if it is a quadrilateral

• A shape is a quadrilateral only if it has four sides

• A shape is a quadrilateral if it has four sides

• A shape is a quadrilateral if and only if it has four sides
