Once you do that elementary trigonometry to find all the points, you can use line() to draw the 2 or 3 lines to form the angle or triangle.
line([x1, x2], [y1, y2]);
But with just a single point at (2,2), you need to define the location of the other 2 points first.
Then use xlim and ylim to set up the axes limits:
xlim([0, 10]);
ylim([0, 10]);
