Example Question #21 : Geometry
If I add another side to the shape below, would that change the name of the shape?
Yes
No
Yes
If I added another side to the pentagon, I would no longer have a five-sided shape, I would have a six-sided shape. By definition, a pentagon has five sides, so if I added another side I would no longer have a pentagon. The number of sides a shape has is an example of a defining attribute, which means it does determine whether or not a shape is a certain shape.
Example Question #21 : Geometry
If I add another side to the shape below, would that change the name of the shape?
Yes
No
Yes
If I added another side to the hexagon, I would no longer have a six-sided shape, I would have a seven-sided shape. By definition, a hexagon has six sides, so if I added another side I would no longer have a hexagon. The number of sides a shape has is an example of a defining attribute, which means it does determine whether or not a shape is a certain shape.
Example Question #22 : Defining Versus Non Defining Attributes: Ccss.Math.Content.1.G.A.1
If I change the color of the pentagon, does that change the type of shape that I have?
No
Yes
No
Changing the color of a shape does not change the type of shape. Color is considered a non-defining attribute, which means no matter what color a pentagon is, it's still a pentagon.
Example Question #21 : Defining Versus Non Defining Attributes: Ccss.Math.Content.1.G.A.1
If I change the color of the rectangle, does that change the type of shape that I have?
Yes
No
No
Changing the color of a shape does not change the type of shape. Color is considered a non-defining attribute, which means no matter what color a rectangle is, it's still a rectangle.
Example Question #21 : Reason With Shapes And Their Attributes
If I cut this rectangle in half, how many pieces will I have?
When we cut something in half, we get equal pieces.
Example Question #22 : Reason With Shapes And Their Attributes
If I cut this circle in half, how many pieces will I have?
When we cut something in half, we get two equal pieces.
Example Question #23 : Reason With Shapes And Their Attributes
If I cut this rectangle into fourths, or quarters, how many pieces will I have?
When we cut something into fourths, or quarters, we get four equal pieces.
Example Question #24 : Reason With Shapes And Their Attributes
If I cut this circle into fourths, or quarters, how many pieces will I have?
When we cut something into fourths, or quarters, we get four equal pieces.
Example Question #25 : Reason With Shapes And Their Attributes
If I cut a rectangle into fourths, how am I changing the size?
The four pieces will be the same size as the rectangle
The four pieces will be different sizes
The four pieces will be bigger than the rectangle
The four pieces will be smaller than the rectangle
The four pieces will be smaller than the rectangle
When we cut something in fourths, we get four smaller pieces that equal each other. If we put those pieces back together, we’d get the original size of the rectangle.
Example Question #26 : Reason With Shapes And Their Attributes
If I cut a rectangle in half, how am I changing the size?
Each piece will be different sizes
Each piece will be the same size as the rectangle
Each piece will be bigger than the rectangle
Each pieces will be smaller than the rectangle, they will be half the size.
Each pieces will be smaller than the rectangle, they will be half the size.
When we cut something in half, we get two smaller pieces that equal each other. If we put those pieces back together, we’d get the original size of the rectangle.
