# TSA CBT Test

### 2D to 3D Interpretation Test

1. In these questions, you are given a flat, 2D shape (often with markings or labels on various segments) and asked to visualize how it would look when folded into a 3D object. You will be asked to match numbers on the faces of the 2D shape to the corresponding letters on the faces of the folded 3D shape.
Take a look at this sample question and see if you can solve it:

A=？
B=?
C=?

A=3
B=2
C=1
Since the 3 face is the only option to “wrap” the circles, it will be A: A=3.
Next, notice that x is one of the squares on the same edge – and since B is vertical to it in the 3D shape, it matches the 2 face of the 2D shape, not the 4. B=2
C is a bit tricky, but you can see that it’s the 1 face by looking at the side of the x: Since x is on the left side of the niche, the upper base must be 1. If the 5 was on the upper base, x would have been to the right. C=1.

2. Which of the possible options represents the shape in its folded form?

Correct Answer:An effective way to answer such questions will be to try and look at the corners of the unfolded shape – the points where 3 lines will meet: The unfolded shape shows that 5,8,9 will share a corner when folded. According to the options, only the last choice follows this role, so it is the correct choice.

### Image Matching

1. In the Shapes Match questions, you are given a target shape and must quickly identify the matching shape from a series of other shapes.
