True or false? Shape A and shape B have the same
number of sides.

Underneath the question, we can see
pictures of two shapes. And both of these shapes have been
made from straight lines. We call these straight lines the
sides of the shape. Our question is made up of a
statement which tells us that shape A and shape B have the same number of sides. In other words, these 2D shapes are
made up of the same number of straight lines.

But this statement might not be
correct. We need to decide whether it’s true
or false. To make sure that we count all the
sides of a shape and also that we only count each one once, let’s trace over them as
we count them. Let’s start from here on shape A,
which is made up of one, two, three, four sides. We can say shape A is a four-sided
shape.

Now, let’s trace over the sides of
shape B. We’ll start from this bottom
corner. There are one, two, three, four
sides again. Although shape 𝐵 is a different
sort of shape to shape A, it’s still a shape with four sides. We’ve counted the number of sides
that make up each shape. And we can see that they’re both
the same. The statement in the question is
true.
