First, we name the given objects using numbers. We can match the objects by looking at the shape of the face. In the object A , the face is similar to a triangle. The object 3 also has face similar to a triangle. So, we match A with 3 . In the object C , the face is similar to a circle. The object 1 also has face similar to a circle. So, we match C with 1 . In the object D , the face is similar to a cylinder. The object 2 also has face similar to a cylinder. Hence, the correct match is shown below.
