Analyzing Conditional Statements in Geometry

This video tutorial by Mr. Backberg covers the basics of conditional statements, including their structure with hypotheses and conclusions. It explains how to rewrite statements in if-then form, apply negation, and understand the converse, inverse, and contrapositive of statements. The tutorial provides examples to illustrate these concepts, helping students grasp logical reasoning and statement manipulation.

What are the two parts of a conditional statement?

• Premise and Conclusion

• Cause and Effect

• Hypothesis and Conclusion

• Statement and Result
