Shapes (2D & 3D)

In your exam, you’ll need to know various shapes and what they look like.

Why?

Because you’re likely going to be asked questions that require knowledge of shapes such as an area or perimeter calculation.

The below is just a quick run through of the shapes and attributes, and we’ll go through the calculation of perimeter and area or volume in more detail in the next checkpoint.

Now, let's go through and talk about the attributes of each of the shapes below (watch video).

In addition to the above shapes, you also have polygons with a certain number of sides (see below).

Aside from the shapes above, you also need to know the various types of 3D shapes like these:

In your exam, the questions that you’ll be asked the require knowledge of shapes are likely to be area or perimeter questions. Rarely are you asked to identify a shape, but you do need to be able to identify a shape in order to answer other questions, so that’s what you’ll do in the following section.

Identify shapes

I am a 3D solid with 6 equal faces

Which shape am I?

A rectangular solid B cube C Cone D cylinder

I am a 3D solid with 1 face

Which shape am I?

A sphere B cube C Cone D cylinder

I am a polygon with 3 sides.

Which shape am I?

A cylinder B triangle C square D rectangle

I am a polygon with 4 sides with no right angles and with only 1 set of parallel lines.

Which shape would I most likely be?

A square B rectangle C parallelogram D trapezoid

Key Rules to remember

• Know the attributes and names of 2D & 3D shapes.
• While the identification of shape questions are not the most common type of questions, you need to know them because they are in other types of questions.

Practice time!

Now, it's your turn to practice.

Click on the button below and start your practice questions. We recommend doing untimed mode first, and then, when you're ready, do timed mode.

Every question has two solutions videos after you complete the question. The first is a quick 60 second video that shows you how our expert answers the question quickly. The second video is a more in-depth 5-steps or less explainer video that shows you the steps to take to answer the question. It's really important that you review the second video because that's where you'll learn additional tips and tricks.

Once you're done with the practice questions, move on to the next checkpoint.

Now, let’s get started on your practice questions.
