How to determine the contrapositive of a conditional statement

The video tutorial introduces the concept of contrapositive in logic, explaining it as a combination of converse and inverse. The teacher uses P&Q to illustrate that the contrapositive is 'not Q then not P'. The lesson applies this concept to vertical angles, demonstrating that if angles are not vertical, then they are not congruent. The session concludes with a recap of the key points discussed.

Explain the relationship between the contrapositive, converse, and inverse.

What is the contrapositive of a statement involving vertical angles?

How would you express 'not Q' in the context of angles?

Discuss the significance of the statement 'if two angles are congruent, then they are not congruent' in logical reasoning.

What does it mean if two angles are not congruent in terms of their contrapositive?
