A Quick Overview of the TSA 2D to 3D Interpretation Test (Read Before Taking the Free Test)

Here’s a quick rundown of what you’ll face in this section of the TSA CBT test.

Go through it before starting the free practice test to get familiar with the question types and the structure of the actual test.

Number of Questions and Time Limits

  • You’ll have 5 to 10 questions on this part, depending on the time you have left after completing the previous test sections – Image Matching and Connect the Dots.
  • The entire exam with all three sections is timed as a whole and you have up to 45 minutes to complete it (the timer follows you as you advance through the sections). So, if you work fast in the first two sections, you’ll have more time for the last and hardest part – the 2D to 3D questions.

Format of the Questions

The 2D – 3D section asks you to match numbers on the 2D image to alphabets on the 3D shape. The questions come in two formats: Multiple Choice (less common) and Fill-in-the-blank (more common).

Structure of the Questions

Let’s quickly analyze how the questions are structured.

First, you have the 2D image. Here’s an example of how it might look on the test:

TSA 2D Image Example

Next to it, you’ll have the corresponding 3D shape. This is the folded version of the 2D shape and you need to compare edges and answer the questions.

The 3D shape can be presented from any viewpoint. Here is the corresponding 3D shape of the 2D image above:

TSA 3D Image Example

Both the 2D and the 3D shapes have a reference point, marked as ‘X’ on one of the faces. This reference point is one of the keys to identifying the correct edges.

Practice doesn’t have to be overwhelming!
Even short sessions with the right materials can make a big difference in your performance. Take it one step at a time, and you’ll feel more confident and ready for test day in no time.

Take the Free TSA 2D to 3D Practice Test

The following 2D to 3D sample questions, taken from our complete practice package, cover both question formats (multiple-choice and fill-in-the-blank) and gradually advance from easier to more difficult questions.

The sample questions below come in two additional formats:

TSA 2D to 3D Multiple Choice Questions

Match the number of the edge in the 2D shape (upper) to the letter of the edge in the 3D shape (lower) below.

Question #1

TSA 2D to 3D Shape Folding Practice Question
Interactive Question

The edge labeled ‘2’ on the 2D net corresponds to what edge on the 3D shape?

The correct answer is E.

Question #2

Let’s see an example of a more challenging multiple-choice question:

TSA TAB Test Sample Question
Interactive Question

The edge labeled ‘8’ on the 2D net corresponds to what edge on the 3D shape?

The correct answer is H.

Mastering the 2D to 3D questions requires practice, repetition, and patience. Your brain needs time to get used to these spatial reasoning questions. Start with simpler shapes and gradually work up to more complex ones.

Our complete practice package offers seven 2D to 3D practice tests with 70 questions, ranging from easy to challenging, providing plenty of practice opportunities to sharpen your skills and master this section.

Let’s continue to the second and more common question type you’ll see on the test: the fill-in-the-blank questions.

TSA 2D to 3D Fill-in-the-Blank Questions

In these questions, you will see similar figures to the multiple-choice questions, but instead of finding just one corresponding number and letter, you’ll need to find between 5 and 12 such edges.

Let’s see an example from our practice package:

Question #3

TSA Test Sample Question
Interactive Fill-in-the-Blank Question

Match the numbers of the edges in the 2D shape (upper) to the letters of the edges on the 3D shape (lower).

A = B = C = D =

E = F = G = K =

The correct answers are:

A = (10)
B = (9)
C = (8)
D = (6)
E = (7)
F = (5)
G = (4)
K = (11)

Now, let’s break it down step by step:

One of the best practices for solving these complex questions is to find the most noticeable 2D face.

You want to spot the most distinctive face on the 2D net that you can easily match to the 3D shape. While there’s always an ‘X’ mark provided, it’s often better to look for something more unique.

For example, in the question above there’s an L-shaped face that acts as the base of the 3D shape. All the faces fold along this L-shape base, which helps you quickly find corresponding edges (D, F, and G), with almost no folding needed.

Let’s try a more challenging question with a more complex design (we’ll walk you slowly through the solution):

Question #4

Shape Folding Practice Question
Interactive Fill-in-the-Blank Question

Match the numbers of the edges in the 2D shape (upper) to the letters of the edges on the 3D shape (lower).

A = B = C = D =

E = F = G = H =

I = J = K = L =

The correct answers are:

A = (2)
B = (1)
C = (6)
D = (10)
E = (11)
F = (9)
G = (8)
H = (7)
I = (12)
J = (13)
K = (3)
L = (14)

Here’s the step-by-step illustration:

This one was pretty hard, right?

Here’s a quick tip to answer this question faster:

Take a look at the reference point (X) on the 2D and 3D shapes above. Its unique shape is visible in the front of the 3D shape, which enables you to quickly find four different edges (F, D, E, C) without even folding one face!

Time management is absolutely critical in this section.

Since the timer follows you throughout the three test sections, once you reach the final 2D to 3D section, you only have about 10 to 20 minutes left.

The seven simulations in our practice package have similar time constraints to help you sharpen your time management skills and get used to working under immense time pressure.

Let’s solve the last 2D-3D practice question, which also includes a complex design:

Question #5

2D - 3D sample Question
Interactive Fill-in-the-Blank Question

Match the numbers of the edges in the 2D shape (upper) to the letters of the edges on the 3D shape (lower).

A = B = C = D =

E = F = G = H =

I = J = K = L =

The correct answers are:

A = 5
B = 6
C = 3
D = 1
E = 8
F = 10
G = 11
H = 12
I = 13
J = 7
K = 9
L = 14

Here’s the detailed illustration:

Ensure You Ace the Two Other TSA Test Sections

While this page focuses on the 2D to 3D test section, let’s take a moment to talk about the first two sections of the test, which candidates often overlook:

Connect the Dots and Speed Image Matching.

These first two sections demand strong attention to detail and quick thinking. The speed at which you finish these sections impacts the time you will have left for the last section – the 2D to 3D (but don’t work too quickly to avoid mistakes).

TSA Connect the Dots

In its basic form, you’ll be asked to connect dots in ascending order: numerically (1-2-3-4…), alphabetically (A-B-C-D…), and alphanumerically (1-A-2-B-3-C…).

As the questions progress, they become much harder and include descending order (from Z to A or 50 to 1) and jump sequences (the difference between letters/numbers will be random).

Let’s see an example from our complete practice package that highly resembles the actual test:

In the practice package, you get 7 Connect the Dots practice tests that cover all the scenarios seen on the actual test and have an infinite number of practice questions (exclusive to this site!).

TSA Speed Image Matching

In this part, you’re given an image and you need to choose its identical match from the answer choices. Try to work as quickly as you can on this section.

Here are examples of the types of questions you’ll face:

TSA Test Image Matching Example

The correct answer is (E).

TSA Test Speed Image Matching Sample

The correct answer is (D).
