Name: Date: 5th Grade Geometry Pre/Post Test ____/6 5.G.B.3: Understand that attributes belonging to a category of two dimensional figures also belong to subcategories of that category. ____/14 5.G.B.4: Classify two-dimensional figures in a hierarchy based on properties. _____/20 points TOTAL Updated 4/30/13 5.G.B.4, 5 points 1) Use the words in the box to complete the tree map to classify polygons. square rhombus isosceles parallelogram polygon trapezoid triangle equilateral scalene rectangle kite quadrilateral polygon quadrilateral parallelogram trapezoid rhombus rectangle square triangle kite scalene SCORING: 5 points=all items correct 4 points= 9-11 correct 3 points= 6-8 correct 2 points=3-5 correct 1 point=1-2 correct 0 points=0 correct iosceles equilateral 5.G.B.3, 4 points 2) Circle True or False for each item, and then justify your answer. True or False: A trapezoid has 2 sides parallel so it must be a parallelogram. How do you know? A parallelogram must have 4 sides parallel (two sets) of parallel sides. Since the trapezoid only has two sides parallel (one set), it is not a parallelogram. True or False: An equilateral triangle is also an isosceles triangle. How do you know?_An equilateral triangle has three congruent sides, and the definition of an isosceles triangle is at least two congruent sides. 5.G.B.4, 2 points 3) Which of the following statements is always true: A rectangle is a square. A parallelogram is a rectangle. A square is a rectangle. Justify your answer (explain). A square is always a rectangle because a rectangle always has four sides, two sets of parallel sides, four right angles, and opposite congruent sides. A square always has all of these attributes. 5.G.B.3, 1 point 4) What are three other names for a square? Answers could include: Rectangle Rhombus Parallelogram Quadrilateral Polygon 5) Classify the triangles and justify your answer. A Right B Acute C Obtuse 5.G.B.4, 6 points How do you know? This triangle has one right angle. _________________________________________________________ _________________________________________________________ A Isosceles B Equilateral C Scalene How do you know? This triangle has two sides that are the same length (congruent). _______________________________________________ _________________________________________________________ CHOOSE ALL THAT APPLY: A Right A Isosceles B Acute B Equilateral C Obtuse C Scalene How do you know? This triangle does not have any sides that are the same length (congruent) and all angles are less than 90.° _________________________________________________________ _________________________________________________________ 5.G.B.3, 1 point 6) Which set of attributes are true of a rhombus? Four sides, two pairs of parallel sides, opposite sides congruent, four right angles. Four sides, one pair of parallel sides, sides not always congruent. Four sides, two pairs of parallel sides, all sides congruent, opposite angles congruent. 5.G.B.4,, 1 point 7) A kite and a parallelogram are both quadrilaterals. What is one difference between these two shapes? Students are expected to list one difference, though they may list more. A parallelogram has opposite sides congruent, and a kite has adjacent sides congruent. A parallelogram has two sets of parallel lines and a kite has no parallel lines. A parallelogram has two sets of opposite congruent angles and a kite has only one set of opposite congruent angles.
