Answer

$(a,a) \in R_1$ for all $a \in R$

Step 1: Analyze the properties of the relation $R_1 = \{(a,b) | a \ge b, a,b \in R\}$ .

Reflexivity: A relation $R_1$ is reflexive if for every $a \in R$ , $(a,a) \in R_1$ . For any real number $a$ , $a \ge a$ is true. Therefore, $(a,a) \in R_1$ for all $a \in R$ . So, $R_1$ is reflexive.
Symmetry: A relation $R_1$ is symmetric if for every $(a,b) \in R_1$ , $(b,a) \in R_1
