Main Difference Between 2D and 3D Shapes

What is a vertex?

• The point where two lines are parallel.

• The point where two lines meet.

• The center point of a circle.

• The longest side of a triangle.

What is an edge in geometry?

• The center point of a shape

• The surface of a 3D object

• Where two sides meet

• A type of mathematical operation

Do edges and sides look the same on 2D shapes?

• Yes, they look the same

• No, they are always different

• Only in triangles

• Only in circles
