I WONDER - What Is A Sphere?

The video tutorial explains the concept of a sphere as a three-dimensional shape that is perfectly symmetrical. It highlights that a sphere's symmetry means that if it is folded in half, both sides will match exactly. This symmetry is consistent regardless of how the sphere is folded, including horizontally. The tutorial emphasizes the uniformity and balance of a sphere's structure.

What is a key characteristic of a sphere as a three-dimensional shape?

• It is a two-dimensional shape.

• It has sharp edges.

• It is perfectly symmetrical.

• It has flat surfaces.

What happens when a sphere is folded in half?

• The two halves become asymmetrical.

• The two halves match perfectly.

• The two halves become flat.

• The two halves do not match.

Why does the direction of folding not matter for a sphere?

• Because it is perfectly symmetrical.

• Because it is not symmetrical.

• Because it is a two-dimensional shape.

• Because it has edges.

Which of the following is true about a sphere's symmetry?

• It only matches when folded vertically.

• It matches regardless of folding direction.

• It only matches when folded horizontally.

• It never matches when folded.

How does a sphere's symmetry affect its appearance when folded?

• It appears asymmetrical.

• It appears with edges.

• It appears perfectly matched.

• It appears flat.
