Use the and basic arithmetic axioms, as demonstrated below:
##{: (color(black)(“Assertion”),” | “,color(black)(“Reason”)), (bar(color(white)(“XXXXXXXXXXXXXX”)),,bar(color(white)(“XXXXXXXXXXXX”))), (|PR|^2=|PS|^2+|SR|^2,” | “,”Pythagorean Theorem”), (|PR|^2=|QR|^2+|PQ|^2,” | “,”Pythagorean Theorem”), (|PS|^2+|SR|^2 = |QR|^2+|PQ|^2,” | “,”Equality Axiom”), (|PS|^2+|SR|^2 = |PS|^2 +|PQ|^2,” | “,”Given: “|PS|=|PQ|), (|SR|^2 = |PQ|^2,” | “,”Subtraction Axiom”), (|SR|=|PQ|,” | “, “Positive Square Roots”) :}##
