00:00:00.940 --> 00:00:03.780
Is the following shape 2D or 3D?
00:00:04.350 --> 00:00:08.730
A shape that is 2D is two-dimensional or it has two dimensions.
00:00:09.180 --> 00:00:12.920
We can also think of it as having two measurements: the length and the width.
00:00:13.760 --> 00:00:15.690
And it’s often called a flat shape.
00:00:16.240 --> 00:00:18.140
3D means it’s three-dimensional.
00:00:18.140 --> 00:00:19.620
There are three dimensions.
00:00:19.980 --> 00:00:24.280
So there will be three measurements, such as length, width, and height.
00:00:25.060 --> 00:00:26.900
And our world is three-dimensional.
00:00:27.420 --> 00:00:31.620
So most of the shapes are like real-life objects that are 3D.
00:00:32.140 --> 00:00:38.850
So looking at our shape, we would have the height, we have the width, but we also have this length.
00:00:39.170 --> 00:00:43.080
So there are one, two, three dimensions.
00:00:43.490 --> 00:00:45.690
Therefore, this shape is 3D.
