|-
|| 00:01
|| Welcome to this tutorial on '''Introduction to GeoGebra'''.

|-
|| 00:05
|| In this tutorial, we will learn, About '''GeoGebra''' interface and geometric tools

|-
|| 00:12
|| To draw parallel and perpendicular lines

|-
|| 00:16
|| To change object properties of a line

About properties of '''Graphics view'''.

|-
|| 00:22
|| Here I am using, '''Ubuntu Linux OS''', version 14.04

|-
|| 00:28
|| '''GeoGebra '''version 5.0.438.0-d

|-
|| 00:33
|| To follow this tutorial, learner should be familiar with basic Mathematics.

|-
|| 00:40
|| To open '''GeoGebra''' applicaton in '''Ubuntu Linux OS''', click on '''Dash Home'''.

|-
|| 00:46
|| In the '''search bar''' type '''geogebra'''.

'''GeoGebra''' icon appears.

|-
|| 00:52
|| Double-click on the icon to open the '''GeoGebra''' application.

|-
|| 00:57
|| Let us open GeoGebra application in '''Windows 10 OS'''.

|-
|| 01:04
|| In '''Search the web and Windows''' box, type '''geogebra'''.

|-
|| 01:09
|| '''GeoGebra '''appears in the list.

|-
|| 01:12
|| Click on it to open the '''GeoGebra '''application.

|-
|| 01:17
|| This is the '''GeoGebra '''interface.

|-
|| 01:20
|| It has a standard '''menu bar''' with menu items,

'''File''', '''Edit''', '''View''', '''Options''', '''Tools''', '''Window''' and '''Help'''.

|-
|| 01:37
|| Below the '''menu bar''', is a '''tool bar''' with various geometric tools.

|-
|| 01:43
|| On the right side of the '''tool bar''', we have '''Undo''', '''Redo''', '''Help''' and '''Preferences''' options.

|-
|| 01:53
|| Below '''tool bar''' we have '''Algebra view''' and '''Graphics view'''.

|-
|| 01:58
|| In '''GeoGebra''', geometry and algebra work side by side.

|-
|| 02:03
|| '''Graphics''' view is used to create geometric figures using tools on the '''toolbar'''.

|-
|| 02:09
|| '''Algebra''' view displays the corresponding algebraic expressions of the drawn figures.

|-
||02:15
|| Using '''View''' menu, we can open or close any view based on our requirement.

|-
|| 02:25
|| At the bottom of the window, we have an '''input bar'''.

|-
|| 02:29
|| We can directly enter algebraic commands and functions using the '''input bar.'''

|-
|| 02:36
|| By default '''grid''' and '''axes''' options are enabled on the '''Graphics view'''.

|-
|| 02:42
|| You can disable the '''axes''' or '''grid''' using the context menu.

|-
|| 02:47
|| Right click on '''Graphics''' view.

The '''Graphics''' menu opens.

|-
|| 02:53
|| In this menu, we have options to check and uncheck '''Axes''' and '''Grid'''.

|-
|| 03:00
|| Let me show you another method to enable or disable the '''axes''' and '''grid'''.

|-
|| 03:05
|| Notice a small arrow triangle next to '''Graphics''', named as '''Toggle Style Bar.'''

|-
|| 03:12
|| Click on the arrow triangle to open the drop-down menu.

|-
|| 03:16
|| Here you will see options to check and uncheck '''axes''' and '''grid'''.

|-
|| 03:22
|| Next we will learn about the '''tool bar ''' in detail.

|-
|| 03:26
|| Let us click on '''Move Graphics View''' tool at the right end of the '''toolbar'''.

|-
|| 03:31
|| Notice that, a dark blue border appears around the tool.

This indicates that the tool is selected.

|-
|| 03:38
|| Hover the cursor on the tool.

Its name and function appears in the tool tip box.

|-
|| 03:45
|| Using this selected tool, we can move the '''Graphics view'''.

Click and drag the '''Graphics view''' as required.

|-
|| 03:53
|| Each tool has a small black triangle at its corner.

|-
|| 03:58
|| When the cursor is placed on the triangle, it turns red.

|-
|| 04:03
|| Let us click on '''Move '''tool on the '''tool bar.'''

A drop-down list of related tools appear.

|-
|| 04:10
|| Let us draw points in the '''Graphics view'''.

|-
|| 04:13
|| Click on '''Point''' tool and then click on the '''Graphics view'''

Point '''A''' is drawn.

|-
|| 04:20
|| Again click to draw another point '''B'''.

|-
|| 04:24
|| Note that the corresponding coordinates of the points appear in the '''Algebra view'''.

|-
|| 04:29
|| Let us learn to draw a line. Click on the triangle at the corner of '''Line''' tool.

|-
|| 04:36
|| Here you can see a list of '''Line''' tools to draw various types of lines.

|-
|| 04:42
|| Using '''Line''' tool, we will draw a line through points A and B.

|-
|| 04:47
|| Click on''' Line''' tool and click on points '''A''' and''' B.'''

|-
|| 04:53
|| Line '''f''' passes through '''A '''and '''B'''.

|-
|| 04:57
|| Let us delete all the '''objects''' on the '''Graphics view'''.

|-
|| 05:01
|| Press '''Ctrl+A''' to select all the objects.

Press '''Delete key '''on the keyboard.

|-
|| 05:08
|| Let us redraw the line '''AB'''.

Click on''' Line''' tool and click on the '''Graphics view'''.

|-
|| 05:17
|| Click again at a different place to draw the line '''AB'''.

|-
|| 05:22
|| Next I will draw a line perpendicular to line '''AB'''.

|-
|| 05:27
|| To do that, click on the '''Perpendicular Line''' tool.

|-
|| 05:31
|| Click above line '''AB''' to draw point '''C''', then click on line '''AB'''.

|-
|| 05:38
|| Line '''g''' passing through '''C''' is perpendicular to line '''AB''' .

|-
|| 05:43
|| Let us draw a line parallel to line '''AB'''.

|-
|| 05:47
|| Click on '''Parallel Line''' tool.

|-
|| 05:50
|| Click below '''AB''' to draw point ''' D''', then click on line '''AB'''.

|-
|| 05:57
|| A line '''h''', parallel to '''AB''' and passing through point '''D''', is drawn.

|-
||06:02
|| Now we will mark intersection points for the two lines.

|-
|| 06:06
|| In the '''Point''' tool drop-down, select '''Intersect''' tool.

|-
|| 06:10
|| Click on the intersection point of the lines '''f''' and '''g'''.

|-
|| 06:15
|| Then click on the intersection point of the lines '''g''' and '''h'''.

|-
|| 06:20
|| Now we will make our drawing a bit interactive.

|-
|| 06:24
|| Click on '''Move''' tool.

|-
|| 06:27
|| Click on point '''A''' and drag.

|-
|| 06:30
|| Notice that points E and F and all lines move along with point '''A'''.

|-
|| 06:36
|| Similarly we will move points '''B''' and '''D'''.

|-
|| 06:40
|| Points '''E , F''' and the lines move along with point '''B'''.

|-
|| 06:45
|| Only point '''F''' and line '''h''' move along with point '''D. '''

|-
||06:50
||Points '''A, B and D''' are independent objects.

|-
|| 06:56
|| Now I will try to move points '''E''' or '''F.'''

We do not see any movement.

|-
|| 07:03
|| This indicates that, points '''E''' or '''F''' are dependent objects.

|-
|| 07:09
|| Now let us change the properties of the lines.

|-
|| 07:13
|| Right click on line '''AB'''.

A context menu opens, with all the properties of the line.

|-
|| 07:21
|| Select '''Object Properties'''.
