Visual Cue	Narration
00.01	Hello and welcome to the spoken tutorial on Question Glues in KTurtle.
00.08	In this tutorial, we will learn the following question glues and, not
00.16	To record this tutorial I am using,Ubuntu Linux OS Version 12.04. KTurtle version 0.8.1 beta.
00.29	We assume that you have basic working knowledge of KTurtle and “if-else” statement in KTurtle
00.39	If not, for relevant tutorials, please visit our website. http://spoken-tutorial.org
00.46	Before proceeding, let me explain about question glue words.
00.51	Question glue words enable us to glue small questions into one big question.
01.00	“and”, “or” and “not” are some glue-words.Glue-words are used together with if-else conditions.
01.11	Let's open a new KTurtle Application.
01.15	Click on Dash home.
01.18	In the Search bar, type KTurtle.
01.22	And Click on the option.
01.24	Let's begin the tutorial with glue word and.
01.28	I already have a program in a text editor.
01.33	Let me copy the code from the text editor and paste it into KTurtle editor.
01.40	Please pause the tutorial here and type the program into your KTurtle editor.
01.46	Resume the tutorial after typing the program.
01.50	Let me zoom into the program text.
01.52	It may possibly be a little blurred.
01.56	Let's look the code.
01.59	reset command sets Turtle to its default position.
02.04	Message in a program is given within double quotes after the keyword message " " .
02.10	“message” command takes “string” as input.
02.14	It shows a pop-up dialog box containing text from the string and also generates a beep for non null strings.
02.24	$a, $b and $c are variables that store user input.
02.30	“ask” command prompts for user input to be stored in variables.
02.36	if(($a+$b>$c) and ($b+$c>$a) and ($c+$a>$b), checks the “if” condition.
02.49	When the two questions glued with “and” are true, result is true.
02.55	'if(($a !=$b) and ($b != $c) and ($c != $a)) checks the if condition.
03.05	when 'if' condition above is true, control moves into nested if block.
03.12	It checks whether sides of triangle are unequal.
03.17	fontsize 18 sets the font size used by print command.
03.22	go 10,100 commands Turtle to go 10 pixels from left of canvas and 100 pixels from top of canvas.
03.35	print command displays the string after checking the if condition.
03.41	else command checks else condition, when if condition in the block is false
03.48	print command displays the string after checking the else condition.
03.54	else command checks the final condition.
03.57	Hereelse is checked only when above conditions are false.
04.03	print command displays the string after checking the else condition. I will run the code to check all the conditions.
04.12	Let's click on the Run button to run the program.
04.15	A message dialog box pops- up.Let me click OK.
04.20	Let's Enter 5 for 'length of AB' and click OK
04.25	8 for 'length of BC' and click OK
04.29	9 for 'length of AC' and click OK
04.33	“A scalene triangle” is displayed on the canvas.
04.37	Lets run again.
04.40	A message dialog box pops up .Let me click OK.
04.44	Lets Enter 5 for length of 'AB' and click OK,6 for length of 'BC' and click OK, 6 for length of 'AC' and click OK.
04.58	“ Not a scalene triangle” is displayed on the canvas.
05.02	Let's run again to check default condition.
05.06	A message dialog box pops up. Let me click ok.
05.11	Let's Enter 1 for length of 'AB' and click OK.
05.16	1 for length of 'BC' and click OK.
05.20	2 for length of 'AC' and click OK.
05.24	" Does not satisfy triangle's inequality " is displayed on the canvas.
05.30	Let's now clear this program. Let me type clear command and run clear command cleans the canvas .
05.40	let's next work with 'not condition.
05.43	Let me copy the program from the text editor and paste it into KTurtle editor.
05.51	Please pause the tutorial here and type the program into your KTurtle editor.
05.56	Resume the tutorial after typing the program.
06.01	Let me zoom into the program text and explain the program.
06.05	reset command sets Turtle to default position.
06.09	$a, $b and $c are variables that store user input.
06.15	if not (($a==$b) and ($b==$c) and ($c==$a))checks the if not condition.
06.27	not is a special question glue-word. It inverses the logical state of its operand.
06.36	e.g. If the given condition is true, not makes it false.
06.42	And when the condition is false the output will be true.
06.48	print command displays the string after checking the if not condition.
06.55	else command is executed when if condition is false.
07.01	print command displays the string after checking the else condition.
07.07	go 100,100 commands Turtle to go 100 pixels from left of canvas and 100 pixels from top of canvas
07.20	repeat 3{turnright 120 forward 100} commands turtle to draws an equilateral triangle on the canvas
07.32	Let me run the program to check all the conditions.
07.36	Press F5 key to run the code.
07.40	Enter 6 for length of AB and click OK
07.45	Enter 5 for length of BC and click OK
07.48	Enter 7 for length of AC and click OK
07.54	“Triangle is not equilateral” is displayed on the canvas.
07.58	Let's run again. Let's enter 5 for length of AB and click ok.
08.05	5 for length of BC and click ok.
08.09	5 for length of AC and click OK
08.13	“Triangle is equilateral” is displayed on the canvas. An equilateral triangle is drawn on the canvas.
08.21	With this we come to the end of this tutorial.
08.25	Let's summarize
08.28	In this tutorial we have learnt, the question glues and not
08.35	As an assignment, I would like you to write program to determine
08.40	Angle concept for right angled triangle using question glue “or”
08.48	Structure of if or condition is:
08.51	if within brackets condition or within brackets condition or within brackets condition.
08.59	Within curly brackets do something.
09.02	else within curly brackets do something.
