Today you'll discover
- how two buildings can share a view
- how another view tells them apart
- why matching views can fool you
Think firstA: tall stack at the back. B: at the front.
Will A and B have the same front view?
Decide first, then press Next. Read the line at the bottom: same or different?
Two buildings on a 2 by 2 base: in A the stack of 2 is at the back left, in B it is at the front left. Their front views are the same, 2 then 1. Their side views differ: 1 then 2 for A, 2 then 1 for B. From above, A covers 3 squares and B covers 4. The last step shows 4 cubes in a square beside 2 cubes on opposite corners.

The big idea
Two different buildings can have the same view, so one view may not be enough.
For exampleA tall stack at the front or at the back gives the same front view. The side view shows which.
Easy to get wrongTwo buildings can even share both a front view and a side view, and differ only from above.
Key word
- same view
- two drawings from the same direction that match square for square

- Find two buildings that share a view.
- Pick the view that tells two buildings apart.
