5.G.3

 

Classify two-dimensional figures into categories based on their properties.

 

5.G.3 Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category.  For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles. 

Attributes Belong to Both Categories and Subcategories

 

Example:

 

Create a Hierarchy Diagram using the following terms:             Possible student solutions:

polygons – a closed plane figure formed from line segments that meet only at their endpoints.

 

quadrilaterals - a four-sided polygon.

 

rectangles - a quadrilateral with two pairs of congruent parallel sides and four right angles.

 

rhombi – a parallelogram with all four sides equal in length.

 

square – a parallelogram with four congruent sides and four right angles.

According to PARCC a trapezoid is defined as “A quadrilateral with at least one pair of parallel sides.”

 

Can you classify a triangle with more than one name? Yes by sides and angles

 

Are parallelograms trapezoids? Yes according to the PARCC definition because a trapezoid is defined as “A quadrilateral with at least one pair of parallel sides.” A Parallelogram has two pairs of parallel sides so that is more than one!

 

Do all quadrilaterals have opposite angles congruent or only certain ones? Not All

 

How many lines of symmetry does a regular polygon have?  The number of lines of symmetry in regular polygons is equal to the number of sides it has.
