  1. Picturing Polygons Review

  2. Definitions: • What is a polygon? • A. A shape with lines • B. A closed figure made up of at least 3 straight sides • C. A quadrilateral or triangle • D. A closed shape

  3. Definitions: • What is a polygon? • A. A shape with lines • B. A closed figure made up of at least 3 straight sides • C. A quadrilateral or triangle • D. A closed shape

  4. Definitions: • What is a scalene triangle? • A. A triangle with 2 equal sides • B. A triangle with 3 equal sides • C. A triangle with no equal sides • D. A triangle with 2 equal angles

  5. Definitions: • What is a scalene triangle? • A. A triangle with 2 equal sides • B. A triangle with 3 equal sides • C. A triangle with no equal sides • D. A triangle with 2 equal angles

  6. Definitions: • True or false: A parallelogram is a type of rhombus.

  7. Definitions: • True or false: A parallelogram is a type of rhombus

  8. Definitions: • What is a trapezoid? • A. A triangle with one pair of parallel lines • B. A quadrilateral with one pair of parallel sides • C. A quadrilateral with one pair of perpendicular lines • D. A triangle with one pair of congruent sides

  9. Definitions: • What is a trapezoid? • A. A triangle with one pair of parallel lines • B. A quadrilateral with one pair of parallel sides • C. A quadrilateral with one pair of perpendicular lines • D. A triangle with one pair of congruent sides

  10. Time to think… • The length of is 10cm. • The width is 8 cm. • The height is 12 cm. • What is my volume?

  11. Explanation • The length of is 10cm. • The width is 8 cm. • The height is 12 cm. • What is my volume? • L X W X H = 960 cubic cm

  12. Time to think… • Find the volume… 5 ft 10 ft *Width for entire object Is 4 ft. 5 ft 15 ft

  13. Explanation • Find the volume… 5 ft 10 ft *Width for entire object Is 4 ft. 10x4x5 = 200 15 x5x4 = 300 5 ft V=500!

  14. Time to think… • What type of angle is this?

  15. Time to think… • What type of angle is this? Obtuse… more than 90°

  16. Time to think… • Mrs. Schuldt says a trapezoid is a polygon that has exactly one set of parallel sides. • Mrs. Nestor says a trapezoid is a polygon that has at least one set of parallel sides. • Which teacher is correct, according to the hierarchy below?

  17. Explanation • Mrs. Schuldt says a trapezoid is a polygon that has exactly one set of parallel sides. • Mrs. Nestor says a trapezoid is a polygon that has at least one set of parallel sides. She’s right because Parallelograms have 2 sets of parallel sides. • Which teacher is correct, according to the hierarchy below?

  18. Time to think… • Which is not a unit cube that could be used to find volume? • A. 1 in x 1 in x 1 in • B. 1 yd x 1 yd x 1 yd • C. 12 in x 12 in x 12 in • D. 2 in x 2 in x 2 in

  19. Time to think… • Which is not a unit cube that could be used to find volume? • A. 1 in x 1 in x 1 in • B. 1 yd x 1 yd x 1 yd • C. 12 in x 12 in x 12 in • D. 2 in x 2 in x 2 in – it must be a set unit of measure- a foot, an inch, a meter, etc.

  20. Time to think… • What names describe the shapes below?

  21. Explanation… • What names describe the shapes below? • Triangle, equilateral, isosceles Quadrilateral, Parallelogram, rectangle, rhombus, square

  22. Explain… • Why is a square a rectangle, but a rectangle not a square?

  23. Explain… • Why is a square a rectangle, but a rectangle not a square? • A square is a rectangle because it has two pairs of congruent sides, two pairs of parallel sides, and four right angles. A rectangle is not a square because it does not have all 4 sides congruent.

  24. Time to think… • Solve this riddle: • I have two pairs of parallel sides. • I have no right angles • All of my sides are the same length. • What am I?

  25. Time to think… • Solve this riddle: • I have two pairs of parallel sides. • I have no right angles • All of my sides are congruent to each other. • What am I? Rhombus

  26. Time to think… • Which word does NOT describe the shape below? • Square • Rectangle • Parallelogram • Quadrilateral

  27. Time to think… • Which word does NOT describe the shape below? • Square • Rectangle • Parallelogram • Quadrilateral
