Because it is big
Because it has 
Because its color is blue
Because it has 
Because it has 
Because it has
A square has 4 equal sides.
Example Question #22 : How To Find The Area Of A Triangle
Why is this shape a triangle?
Because the 
Because its color is blue
Because it has 
Because it has 
Because it is smaller than a square
Because it has
A triangle has 
Example Question #12 : Geometry
If I make the triangle below bigger, does that change the type of shape that I have?
Yes
No
No
Changing the size of a shape does not change the type of shape. Size is considered a non-defining attribute, which means no matter how big or small a triangle is, it's still a triangle.
Example Question #13 : Geometry
If I make the square below bigger, does that change the type of shape that I have?
Yes
No
No
Changing the size of a shape does not change the type of shape. Size is considered a non-defining attribute, which means no matter how big or small a square is, it's still a square.
Example Question #14 : Geometry
If I make the rectangle below bigger, does that change the type of shape that I have?
No
Yes
No
Changing the size of a shape does not change the type of shape. Size is considered a non-defining attribute, which means no matter how big or small a rectangle is, it's still a rectangle.
Example Question #1341 : Common Core Math: Grade 1
If I make the square below smaller, does that change the type of shape that I have?
Yes
No
No
Changing the size of a shape does not change the type of shape. Size is considered a non-defining attribute, which means no matter how big or small a square is, it's still a square.
Example Question #16 : Geometry
If I make the rectangle below smaller, does that change the type of shape that I have?
Yes
No
No
Changing the size of a shape does not change the type of shape. Size is considered a non-defining attribute, which means no matter how big or small a rectangle is, it's still a rectangle.
Example Question #11 : Reason With Shapes And Their Attributes
If I make the triangle below smaller, does that change the type of shape that I have?
Yes
No
No
Changing the size of a shape does not change the type of shape. Size is considered a non-defining attribute, which means no matter how big or small a triangle is, it's still a triangle.
Example Question #18 : 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 triangle, I would no longer have a three-sided shape, I would have a four-sided shape. By definition, a triangle has three sides, so if I added another side I would no longer have a triangle. 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 #11 : 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 square, I would no longer have a four-sided shape, I would have a five-sided shape. By definition, a square has four sides, so if I added another side I would no longer have a square. 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.
