9-3: Classifying Polygons Logic Activity #1) Do I Exist? Explain why or why not! •I am a trapezoid •I have two angles that each measure 45˚ •I have two other angles that each measure 135˚ #1) Answer: Yes! •A trapezoid can have 2 acute angles and 2 obtuse angles, as long as the angles add up to 360˚. • 135(2) + 45(2) = 360˚ #2) Do I Exist? Explain why or why not! •I am a parallelogram •I have angles measuring: 100˚, 105˚, 65˚, and 90˚ #2) Answer: No! •Parallelograms need to have two pairs of equal angles. #3) Do I Exist? Explain why or why not! •I am a rhombus, quadrilateral, and parallelogram all at the same time! #3) Answer: Yes! •A rhombus is a quadrilateral because it has 4 sides. •A rhombus is a type of parallelogram with 4 equal sides. #4) Do I Exist? Explain why or why not! •I have to be a square if I’m a parallelogram and all of my sides are the same length. #4) Answer: No! •I could also be a rhombus! #5) Do I Exist? Explain why or why not! •I am a scalene triangle with angles measuring: 75˚, 35˚ and 70.5˚ #5) Answer: No! •The sum of the angles exceed 180˚ and a triangle measures exactly 180˚ inside. #6) Do I Exist? Explain why or why not! •I am a scalene triangle with side lengths of 14 inches, 4 inches, and 2 inches. #6) Answer: No! •If you draw the triangle, the sides cannot connect with the given measurements! #7) Do I Exist? Explain why or why not! •I am an isosceles triangle with angle measurements of: 50˚, 50˚ and 80˚ #7) Answer: Yes! •Isosceles triangles need to have 3 angles which add up to 180˚ •Two of the angles need to be congruent #8) Do I Exist? Explain why or why not! •I can be a rectangle, parallelogram, quadrilateral, and a regular polygon all at the same time. #8) Answer: Yes! •A rectangle is 4-sided •A rectangle has opposite angles and sides congruent •A rectangle has both pairs of opposite sides parallel #9) Do I Exist? Explain why or why not! •All rectangles are squares. #9) Answer: No! •A rectangle may not be a square because all of the sides may not be congruent #10) Do I Exist? Explain why or why not! •All squares are rectangles. #10) Answer: Yes! •A rectangle is a parallelogram whose sides intersect at 90° angles. •A rectangle is a parallelogram with opposite sides congruent. #11) Do I Exist? Explain why or why not! •A square is a rhombus. #11) Answer: Yes! •A square is a four-sided shape •A square has all sides congruent •Opposite sides are parallel •Opposite angles are equal #12) Do I Exist? Explain why or why not! •A trapezoid can be a parallelogram. #12) Answer: No! •A trapezoid does not have two pairs of parallel sides, only one. #13) Do I Exist? Explain why or why not! •Every parallelogram is made up of two triangles. #13) Answer: Yes! •180˚ + 180˚ = 360˚ •Draw any quadrilateral, and you can divide it into 2 triangles
