No, opposite angles are not congruent; consecutive angles are not supplementary. 1 - $200 Am I a parallelogram? Why? Yes; both pairs of opposite side are parallel and congruent. 1 - $300 Am I a parallelogram? Why? Yes, one pair of sides is both parallel and congruent. 1 - $400 Am I a parallelogram? Why? No; one pair of sides is congruent and one pair is parallel; need to know both pairs are either. 1 - $500 Am I a parallelogram? Why? Yes; diagonals bisect each other. 2 - $100 I am a parallelogram.

I have a minimum of three straight sides. All polygons…. triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon, decagon ….etc. 5 - $100 What is the relationship between the slopes of parallel lines? The slopes are the SAME!! 5 - $200 What is the relationship between the slopes of perpendicular lines? The slopes are opposite reciprocals OR when the slopes are multiplied together the answer is -1 5 - $300 Which is true? A square is always a rectangle. A rectangle is always a square. A SQUARE IS ALWAYS A RECTANGLE BUT…. A RECTANGLE IS ONLY SOMETIMES A SQUARE!! 5 - $400 List three types of quadrilaterals. parallelogram, rectangle, rhombus, square, kite, trapezoid, isosceles trapezoid. 5 - $500 List all the properties of a parallelogram. opposite sides are parallel opposite sides are congruent opposite angles are congruent consecutive angles are supplementary diagonals bisect each other Final Jeopardy What are the similarities and differences between parallelograms and rectangles? A rectangle is a parallelogram. Therefore has all the properties of a parallelogram: opposite sides parallel, opposite sides congruent, opposite angles congruent, consecutive angles supplementary and diagonals bisect each other. In addition, a rectangle has four congruent right angles and congruent diagonals.
