This is two questions. Question 1) The Transitive Property of Equality is defined by the statement: if A is equal to B and B is equal to C, then A is equal to C. So, for the first statement given, the complete expression is: if TX = XY and XY = YZ, then TX = YZ (this is the option C.) Question 2) The property ilustrated by the statement if KL = LM, then LM = KL, is the reflexive property of the equality. It means that every element (may be segment) is equal to itself.
