1
00:00:04,269 --> 00:00:10,089
We'll see today how to create a reflection using the GeoGebra program.

2
00:00:10,810 --> 00:00:13,550
Okay, this is the exercise I have shared with you.

3
00:00:13,990 --> 00:00:24,329
And to open it and edit it, you have to go here over these three dots, click, and then open with GeoGebra.

4
00:00:24,829 --> 00:00:26,730
Okay, that way you can edit everything.

5
00:00:29,570 --> 00:00:30,629
Okay, and here we are.

6
00:00:30,629 --> 00:00:41,270
This is the skull I have to decorate, and to do so, I can either use this tool, polygon, or the pencil that we will see in a bit.

7
00:00:42,329 --> 00:00:52,270
To create a polygon, just click on that, make any random figure that you like, for example, a star, and close it.

8
00:00:52,590 --> 00:01:00,130
Now, this looks very ugly because it has all of the tags, all of the letters, and I don't want it to look that way.

9
00:01:00,630 --> 00:01:07,469
So I'm going here to Edición, and I'm going to click on this tool, Hide or Show an Object.

10
00:01:07,950 --> 00:01:15,829
I click on that, and then I click over each and every point there is.

11
00:01:17,069 --> 00:01:24,870
When I change my tool back again to the arrow, the Move tool, the points disappear and I have a clear star.

12
00:01:24,870 --> 00:01:32,689
okay now if i want to change the color of my star i have to click on it with the move tool

13
00:01:32,689 --> 00:01:39,709
and i have four options and then three dots i'm going to click on the first one which looks like

14
00:01:39,709 --> 00:01:48,370
a bucket of paint and here i have seven seven different colors and a plus and a bar here this

15
00:01:48,370 --> 00:01:55,230
is the opacity level, okay? The transparency of the color. And I want it to be full, so I set it

16
00:01:55,230 --> 00:02:03,609
at 100. And then I can either choose one color here, or I can go to the plus button and choose

17
00:02:03,609 --> 00:02:13,210
any of these. In this case, I'm going to choose this light yellow, okay? Cool. Now I have one

18
00:02:13,210 --> 00:02:21,530
ornament and i want to reflect it on the other side so i'm going below to transformation tools

19
00:02:22,090 --> 00:02:28,650
and here i have translation which we did the other day but the complicated way and i have also

20
00:02:28,650 --> 00:02:34,569
rotation and symmetry there's two kinds of symmetry okay i'm going to pick the first one

21
00:02:34,569 --> 00:02:39,849
which uses an axis so with that tool clicked

22
00:02:39,849 --> 00:02:43,930
i go to the star click and then to my axis

23
00:02:43,930 --> 00:02:50,569
me which is this straight line and the star duplicates reflected on the

24
00:02:50,569 --> 00:02:55,449
other side okay okay i'm going to do the same using

25
00:02:55,449 --> 00:03:01,930
another tool take the pencil tool which is here behind

26
00:03:01,930 --> 00:03:09,610
my portrait and there's this one below others lapis and for example i'm going to draw this

27
00:03:10,490 --> 00:03:18,409
kind of flower around the school eye and this shape this is not actually a shape this is going

28
00:03:18,409 --> 00:03:28,409
to be a line and as such i can only color the line not the interior space okay once i have it

29
00:03:29,289 --> 00:03:35,210
I can go with the move tool. I don't have any letter tags because there's no point

30
00:03:36,729 --> 00:03:43,689
and I can change the color again just the color of the line because it hasn't got any depth.

31
00:03:43,689 --> 00:03:48,889
I'm going to choose that color for example click anywhere on the screen and now I'm going to

32
00:03:48,889 --> 00:03:56,889
reflect it on the other side. I go to Transformaciones, Transformations here,

33
00:03:57,509 --> 00:04:04,229
Simetria Axial, click on my flower, click on the straight line, and there I've got it.

34
00:04:04,930 --> 00:04:12,189
Now, to save this on my GeoGera account, right now you can see I'm not in my account, but I would go

35
00:04:12,189 --> 00:04:16,529
here and click as save, guardar, just that.

36
00:04:16,529 --> 00:04:21,009
But if I want to upload it to Classroom as an image,

37
00:04:21,009 --> 00:04:24,730
I have to click here, export that image.

38
00:04:24,730 --> 00:04:26,689
Export the image.

39
00:04:26,689 --> 00:04:31,870
I click, then a screenshot of the paper,

40
00:04:31,870 --> 00:04:34,589
of the part of the screen I'm seeing is saved,

41
00:04:34,589 --> 00:04:40,449
and I can download it to my folder, and that is that.
