If you take level slices of a 2D object, then most level slices should have 1 dimensions. If you take level slices of a 3D object, then most level slices should have 2 dimensions. If you take level slices of a 4D object, then most level slices should have 3 dimensions. 0

If you are looking at an object's level slices and most of them are 0D, then you know the object will have 1 dimension(s). If you are looking at an object's level slices and most of them are 1D, then you know the object will have 2 dimension(s). If you are looking at an object's level slices and most of them are 2D, then you know the object will have 3 dimension(s). If you are looking at an object's level slices and most of them are 3D, then you know the object will have 4 dimension(s). 1 2 3 4 0.1 / 0.1 pts Question 3 The boundary of a 1D triangle is 2 vertices (also known as 0D triangles).
