• Prove that
• The points (0, 3), (1, 2), (3, 4), (2, 5) make a rectangle
• Prove that
• The points (1, 3), (3, 2), (4, 4), (2, 5) make a square
• Prove that
• The points (-1, 3), (7, 3), (6, 4), (-2, 4) make a parallelogram
• What shape?
• Both the bottom and right side are 3 units. The left and right side are congruent. The top and bottom are parallel
• What shape?
• Both the bottom and right side are 3 units. The left and right side are congruent. The left and right are parallel
Rhombus
• What shape?
• The diagonals are congruent and perpendicular
Square
• What shape?
• The top and the bottom both measure 8.25, the top line has a slope of 1/4 and the bottom line has a slope of 0.25
Parallelogram
• What shape?
• Both pairs of opposite angles are congruent to each other. The diagonals bisect each other
Parallelogram

• Find x (assume //ogram) X = 9
• Find x (assume //ogram) X = 7
• Find x (assume //ogram) X = 6
• Find x (assume //ogram) X is unsolvable
• Find x (assume rectangle) X = 5
• Find x (assume rectangle) X = 30°
• Find x (assume rectangle) X = 5
• Find x (assume rectangle) X = 7.5
