Clipart images of right and oblique triangles that can be used with trigonometry problems involving solving triangles. There are also several images that can be used for application problems (crossing a river, lake, city block). For more triangles that can be used in trigonometry, see the Right Triangles, Misc. and the Triangles, Misc. galleries.
