Draw a triangle
Difficulty: 
Create a program that allows you to draw a triangle by implementing the drawTriangle() method. Note that the triangle consists of 3 individually drawn lines.
The location of the triangle on the screen is something you are allowed to hard code. So just an invocation of the drawTriangle() method should be enough to display the triangle on the screen.
Example
You can use the image below to figure out how to calculate the triangle coordinates.
