1.) Given the coordinates of a segment, how is the distance formula used to find the length of the segment? Instead of using the distance formula, would it be easier to use the Pythagorean Theorem? Explain.

2.) If you know the coordinates of the endpoints of a segment, does it matter which point is represented by (x₁, y₁)? Why? Explain.

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
