What will the same slopes tell you about the quadrilateral?

• Opposite sides are parallel

• Opposite sides are congruent

• Diagonals are congruent

• Diagonals bisect each other

How do you show diagonals are perpendicular?

• They would have opposite reciprocal slopes

• They would have the same slope

• They would have the same midpoint

• They would look perpendicular

How do you show consecutive sides are perpendicular?

• They would have opposite reciprocal slopes

• They would have the same slope

• They would have the same midpoint

• They would look perpendicular

What conclusion would you make if the you calculated the slopes to be this?

• Opposite sides parallel

• Consecutive sides or Diagonals are perpendicular

• Opposite sides are congruent

• none of these
