Name: GEOMETRY AND SPATIAL SENSE: CLASSIFYING QUADRILATERALS R EMEMBER ! A quadrilateral is any polygon with four sides. A trapezoid is a quadrilateral with one pair of parallel sides. A parallelogram is a quadrilateral with two pairs of parallel sides. A rhombus is a parallelogram with four equal sides. A rectangle is a parallelogram with four 90º (right) angles. A square is both a rhombus and a rectangle. 1. In the following chart, complete each blank with the correct number or word. This shape appears to have… _______ pairs of parallel sides. _______ pairs of equal sides. _______ right angles. This shape appears to have… _______ pairs of parallel sides. _______ pairs of equal sides. _______ right angles. I think this shape is a ___________. I think this shape is a ___________. This shape appears to have… _______ pairs of parallel sides. _______ pairs of equal sides. _______ right angles. This shape appears to have… _______ pairs of parallel sides. _______ pairs of equal sides. _______ right angles. I think this shape is a ___________. I think this shape is a ___________. 2. In the table below, print the letter of each shape in every column in which it appears to belong. One column has been done for you. A B E Quadrilateral F Trapezoid Parallelogram B, C, F, G, H C D G Rhombus H Rectangle Square 3. Play Call of Geometry: Quadrilateral Warfare! Go to mathfrog.ca for the link. Expectation: i) identify and compare different types of quadrilaterals The same number of ticks on two lines means these lines are equal in length. The same number of arrows on two lines means these lines are parallel. A square in a corner of a shape means the corner is a right angle ( 90 0 ). 4. Complete this chart. Labelled Quadrilateral Name Characteristics 5. trapezoid square - four equal sides - two pairs of parallel sides -four sided figure In each blank below, print the best name for that shape. Your choices are square, rectangle, parallelogram, quadrilateral, trapezoid, and rhombus. The diagram to the right should help you. Four sides Quadrilaterals Trapezoids One pair of parallel sides Parallelograms Two pairs of parallel sides Rectangles Squares Four right angles Rhombi Four equal sides Four equal sides Four right angles Which Shape Am I? 1. I am NOT a parallelogram but I have one pair of parallel sides. __________________ 2.Two of me are made if a straight line connects opposite corner points(vertices) of a quadrilateral. __________________ 3. If I am NOT a rhombus, can I be a square? ____Why/why not?__________________________ 4. If I am a parallelogram, am I always a trapezoid? ____________________________________ Expectation: i) identify and compare different types of quadrilaterals
