Identifying Shapes by Classification

This lesson teaches how to identify the attributes of shapes using their classifications. It covers the properties of quadrilaterals, including parallelograms, rectangles, squares, and rhombuses. The lesson explains how these shapes share attributes, such as having four sides and pairs of congruent sides. It also demonstrates how to use this knowledge to solve problems, like drawing shapes with specific attributes. The lesson concludes by reinforcing the understanding of shape attributes and their classifications.

• It has no parallel sides.

What must a square have to be classified as a rectangle?

• Four sides and no right angles

• Four sides and four right angles

• Three sides and three right angles

• Four sides and two right angles

Which attribute is shared by both rhombuses and parallelograms?

• All sides are different lengths

• All angles are right angles

• Opposite sides are parallel

• No sides are parallel

What shape can have exactly two pairs of congruent sides?

• Circle

• Pentagon

• Triangle

Which of the following shapes is not a member of the parallelogram family?
