• I can 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.

3. Pre-Check
1. Shapes can fit into more than one category when thinking about
their properties.
2. Geometric shapes can be general and get more and more specific.
3. Parallel sides have the same distance between them with out ever
touching each other.
4. A rhombus has opposite angles that are equal.
5. A rectangle has two right angles.
6. A square is a rectangle, parallelogram, quadrilateral, and polygon.
7. A circle is a quadrilateral.
8. A parallelogram is a polygon.
9. A kite is a quadrilateral.
10. A square has four equal sides and four right angles.

• Shapes can fit into more than one
category.
• We can identify and describe properties of
two-dimensional shapes more precisely

8. • Where is geometry found in your everyday world?
• How can plane figures be categorized and classified?
• What is a quadrilateral?
• How can you classify different types of quadrilaterals?
• How are quadrilaterals alike and different?
• What are the properties of quadrilaterals?
• Why are some quadrilaterals classified as parallelograms?
• Why is a square always a rectangle?

• Congruent- same size same shape

13. • Right angle: An angle of 90 degrees
square rectangle
• Quadrilateral: A figure with four sides

19. • Cut each shape. Label the shape and write an explanation explaining
why each shape belongs on the poster of your choice.
• Use your resources, notes, and discussion to classify each shape on
the correctly.
• Make a Geometric shape posters. Use shape and write the
properties of each. You may cut them if needed to create:
Polygons
Trapezoids
Rhombuses
Squares
Rectangles
Triangles
