The pattern of triangles is randomly generated, and not intended to form a picture. If you get stuck, the "hint" feature can tell you if a triangle should be black or white. With "hint" selected, just click on the triangle you want a hint for. When you're done, click "solution" to check your work. This is a one-size-only version of Trinograms. If you want to change puzzle sizes, you will need to get the the full version.
