How to make Triangle in Python Turtle using onscreenclick? Last Updated : 15 Jul, 2025 Comments Improve Suggest changes Like Article Like Report “Turtle” is a Python feature like a drawing board, which lets us command a turtle to draw all over it! We can use functions like turtle.forward(…) and turtle.right(…) which can move the turtle around. Turtle is also Known as Logo Programming language which commands for movement and drawing produced line or vector graphics, either on screen or with a small robot termed a turtle. Functions usedTurtle(): This Method is used to make object. onscreenclick(functionname,1): This turtle function which sends the current coordinate to function which further utilise to form triangle, 1 is for left click and 3 is for Right click speed(): This is used to increase or decrease the speed of turtle pointer. listen(): This allows the server to listen to incoming connections. done(): This is used to hold the screen. penup(): This is built in function in turtle library to draw out the line. pendown(): This is built in function in turtle library to draw in the line. forward(): This is built in function in turtle library to move turtle forward direction.it takes pixel unit as an argument left(): This is built in function in turtle library to turn turtle left direction.it takes angle in degree as an argument Python3 import turtle # Screen() method to get screen wn=turtle.Screen() # creating tess object tess=turtle.Turtle() def triangle(x,y): # it is used to draw out the pen tess.penup() # it is used to move cursor at x # and y position tess.goto(x,y) # it is used to draw in the pen tess.pendown() for i in range(3): # move cursor 100 unit # digit forward tess.forward(100) # turn cursor 120 degree left tess.left(120) # Again,move cursor 100 unit # digit forward tess.forward(100) # special built in function to send current # position of cursor to triangle turtle.onscreenclick(triangle,1) turtle.listen() # hold the screen turtle.done() Output : As we can see cursor forms triangle where we can Comment More infoAdvertise with us Next Article Must Do Coding Questions - Topic-wise S sunnyyadav1309 Follow Improve Article Tags : Python Python Programs Python-turtle Practice Tags : python Similar Reads Interview PreparationInterview Preparation For Software DevelopersMust Coding Questions - Company-wise Must Do Coding Questions - Topic-wiseCompany-wise Practice ProblemsCompany PreparationCompetitive ProgrammingSoftware Design-PatternsCompany-wise Interview ExperienceExperienced - Interview ExperiencesInternship - Interview ExperiencesPractice @GeeksforgeeksProblem of the DayTopic-wise PracticeDifficulty Level - SchoolDifficulty Level - BasicDifficulty Level - EasyDifficulty Level - MediumDifficulty Level - HardLeaderboard !!Explore More...Data StructuresArraysLinked ListStackQueueBinary TreeBinary Search TreeHeapHashingGraphAdvance Data StructuresMatrixStringAll Data StructuresAlgorithmsAnalysis of AlgorithmsSearching AlgorithmsSorting AlgorithmsPattern SearchingGeometric AlgorithmsMathematical AlgorithmsRandomized AlgorithmsGreedy AlgorithmsDynamic ProgrammingDivide & ConquerBacktrackingBranch & BoundAll AlgorithmsProgramming LanguagesCC++JavaPythonC#Go LangSQLPHPScalaPerlKotlinWeb TechnologiesHTMLCSSJavaScriptBootstrapTailwind CSSAngularJSReactJSjQueryNodeJSPHPWeb DesignWeb BrowserFile FormatsComputer Science SubjectsOperating SystemsDBMSComputer NetworkComputer Organization & ArchitectureTOCCompiler DesignDigital Elec. & Logic DesignSoftware EngineeringEngineering MathematicsData Science & MLComplete Data Science CourseData Science TutorialMachine Learning TutorialDeep Learning TutorialNLP TutorialMachine Learning ProjectsData Analysis TutorialTutorial LibraryPython TutorialDjango TutorialPandas TutorialKivy TutorialTkinter TutorialOpenCV TutorialSelenium TutorialGATE CSGATE CS NotesGate CornerPrevious Year GATE PapersLast Minute Notes (LMNs)Important Topic For GATE CSGATE CoursePrevious Year Paper: CS exams Like
