Slice a square pyramid parallel to the base

Step by step

The question

Question: what shape is the cut, if we slice a square pyramid parallel to the base?

A cross section is the flat face we see when we slice a solid.

1 Look at the cut

Here is the square pyramid.

We slice it parallel to the base.

The red face is the cut.

2 Name the shape

Flat, the cut looks like this.

Parallel to the base, the cut is a square like the base, but smaller.

So it is a square.

Careful!

A cut parallel to the base always has the shape of the base.

3 Check

Let's check: a cut parallel to the base has the shape of the base.

So the answer is right!

Let's look back.

First: look at the cut.

Then: name the shape.

Last: check.
