This educational guide delves into the characteristics of quadrilaterals, emphasizing that shapes like rhombuses, rectangles, and squares share common attributes, such as having four sides. Students will learn to recognize these shapes as part of the broader category of quadrilaterals and will create examples of quadrilaterals that do not fit neatly into these subcategories. The guide includes definitions of key terms, such as parallelograms, trapezoids, rectangles, rhombuses, and squares, to help students understand plane shapes and their properties better.

GeometryHow can I describe the attributes of quadrilaterals/shapes?
Standard MCC3.G.1Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g. quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
What is a quadrilateral? • A quadrilateral is a 4 sided polygon.
Glue the quadrilateral page in your math journal. Parallelogram -2 sets of parallel sides -2 sets of congruent sides Trapezoid -4 sides -only 1 set of parallel sides
Rectangle 2 sets of parallel sides 2 sets of congruent sides Rhombus 4 congruent sides 2 sets of parallel sides
Square 4 congruent sides 2 sets of parallel sides
