Pygame Draw Triangle

Python has a simple pen drawing library called turtle. Using simple movement commands, we can draw shapes using the python turtle library. When teaching python to children, turtle is a good library to introduce to get children excited about the language and its features.

The basic actions used in the following examples are,

With this function you can draw either an outline of a triangle or a filled triangle. Example: drawsetcolour(caqua); drawtriangle(50, 50, 200, 50, 50, 200, 0); This will draw a filled aquamarine-coloured isosceles right-angled triangle, with its first corner at. Draw a trigon/triangle: pygame.gfxdraw.aatrigon. See the pygame.draw pygame module for drawing shapes module for alternative draw methods. The pygame.gfxdraw module differs from the pygame.draw pygame module for drawing shapes module in the API it uses and the different draw functions available.

Draw a line with pen – forward() command
Move without drawing – penup(), pendown() commands
Turn the pen to an angle – left(), right() commands

The following python program draws a simple equilateral triangle,

Pygame Polygon

The following python program draws a right angled triangle,

The following python program draws a star shape by drawing two identical isosceles triangles,

A. Write a triangle solver that takes 3 inputs consisting of angles in degrees and length
of sides in arbitrary units and, if possible (your program has to determine this),
supplies all other angles and side lengths. There will be either 0 triangles, 1 triangle,
2 triangles or an infinite number of triangles – you program must determine which
possibility. Classify the type of triangle (right triangle, isosceles, equilateral, acute,
obtuse – see any good geometry book. Finally, use the Turtle module to draw the
triangle(s) with correct relative dimensions.
