Example Question #17 : Geometry

If I add another side to the shape below, would that change the name of the shape? 

1

Possible Answers:

No

Yes

Correct answer:

Yes

Explanation:

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 #18 : Geometry

If I add another side to the shape below, would that change the name of the shape? 


2

Possible Answers:

No

Yes

Correct answer:

Yes

Explanation:

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.
