WebIn particular, we define the reflexive, symmetric, and transitive properties. We will use directed graphs to identify the properties and look at how to prove whether a relation is reflexive, symmetric, and/or transitive. 🔗 Definition 8.2.1. Let R R be a relation on A. A. Then R R is reflexive if for all x ∈ A, x ∈ A, xRx. x R x. WebOct 29, 2024 · No: you can see that 2 R 4 and 4 R 2, but 2 ≠ 4. Transitivity. Suppose x R y and y R z; you want to prove that x R z. So, suppose t is a prime with t ∣ x; then t ∣ y, because of x R y, and therefore t ∣ z, because of y R z. The condition that x R z has been verified. Try the others.

We can then conclude that the proposition cannot be false, and hence, must be true. When we assume a proposition is false, we are, in effect, assuming that its negation is true.
