Which of the given shapes has four
sides?

We’re shown a picture here of four
different 2D or flat shapes. We can see that each of the shapes
is made up of a number of straight lines. We call these straight lines the
sides of the shape. Now, each of these shapes has a
different number of sides. But we’re asked to find the shape
that has four sides. Let’s count the sides on each shape
to find out which one it is.

We could put a counter on each side
to show that we’ve counted it. The first shape has one, two,
three, four, five sides. This isn’t the shape we’re looking
for. We’re looking for a four-sided
shape. Let’s try the next one. Do you recognize this next
shape? It’s a triangle. And the one thing that we can say
about triangles is that we can draw them by joining up three straight lines. They have three sides. So, this isn’t our shape
either.

Our third shape has one, two,
three, four sides. It looks like this is the shape we
were looking for. And if we just check the final
shape, we can see that this has six sides. So, we’ve identified the shape that
has four sides. And you know what the name of that
shape is? It’s a square. Each of the four sides is the same
length. And if you think that this doesn’t
look like the usual way you draw a square, turn your head slightly. This is just a square that’s been
turned a bit. That’s all. This is the shape that has four
sides.
