00:00:00,670 --> 00:00:06,340
Let's continue our discussion on basic terms and concepts in geometry in this video.

2
00:00:06,370 --> 00:00:09,220
Let's quickly visit what we mean with a plane.

3
00:00:09,430 --> 00:00:12,930
A plane is a flat surface, for example.

4
00:00:13,090 --> 00:00:17,430
Your computer screen is a plane or your mobile screen is a plane.

5
00:00:17,710 --> 00:00:21,010
Now, a plane is a two dimensional figure.

6
00:00:21,350 --> 00:00:23,740
So it has length and it has.

7
00:00:23,740 --> 00:00:27,250
But that's why we call it a two dimensional shape.

8
00:00:27,650 --> 00:00:29,150
Now, what about lines?

9
00:00:29,380 --> 00:00:30,900
Lines are one dimensional.

10
00:00:31,120 --> 00:00:32,680
They just have length.

11
00:00:33,010 --> 00:00:36,180
Now, another example of a plane is your table.

12
00:00:36,190 --> 00:00:37,900
Say you're studying on this table.

13
00:00:38,110 --> 00:00:42,340
You will notice that this surface of your table is airplane.
