Geometry: Law of Detachment Printable Practice Worksheet w/ Key

Product Description
Are your students having trouble with the Law of Detachment when they are working with formal logic? Most students are good and determining whether statements are true or false but they struggle with determining whether or not statements are valid or invalid based on the Law of Detachment. This document contains 20 basic statements that the students analyze to determine if the conjecture is valid or invalid. For example they are set up as follows:

If Bob cuts the lawn he will earn \$10 from his mother.
Given: Bob earned \$10 from his mother.
Conjecture: Bob cut the lawn.

*This example is invalid.

I have included a full answer key with explanation of the topic. If this is your first time teaching this is can be hard to explain to the students and hopefully this will help. These 20 problems are fairly repetitive but can be good for first time logic learners.

Please check out my other resources for both Algebra and Geometry classes and feel free to contact me if you have any special resource requests.

If you find this product helpful I would appreciate any feedback you would be willing to leave.

Thanks and happy teaching!
