This worksheet asks you to sort the given attributes into two categories: "Defining Attribute" and "Non-defining Attribute". To solve this, I need to understand what these terms mean in the context of geometry.
-
Defining Attributes are characteristics that are essential to a shape's identity. If you change a defining attribute, the shape becomes a different type of shape. For example, the number of sides or angles defines whether a shape is a triangle, square, or pentagon.
-
Non-defining Attributes are characteristics that can be changed without altering the fundamental identity of the shape. These include things like size, color, or orientation (how it's turned).
Now, let's analyze each attribute listed on the worksheet:
1.
Size: A large square is still a square, and a small square is still a square. Changing the size doesn't change its identity. This is a
Non-defining Attribute.
2.
Color: A red circle is still a circle, and a blue circle is still a circle. The color doesn't define the shape. This is a
Non-defining Attribute.
3.
Sides: The number of sides is crucial. A shape with 3 sides is a triangle; a shape with 4 sides is a quadrilateral. This is a
Defining Attribute.
4.
Orientation: A square rotated 45 degrees is still a square. Its orientation doesn't change what kind of shape it is. This is a
Non-defining Attribute.
5.
Closed: A shape must be closed to be considered a polygon (like a square or triangle). An open shape is fundamentally different. This is a
Defining Attribute.
6.
Corners: The number of corners (or vertices) corresponds directly to the number of sides and is essential for defining a shape (e.g., a triangle has 3 corners). This is a
Defining Attribute.
Based on this analysis, here is the solution:
---
Defining Attribute
- Sides
- Closed
- Corners
Non-defining Attribute
- Size
- Color
- Orientation
Parent Tip: Review the logic above to help your child master the concept of defining and non defining attributes of shapes worksheet.
