This may be constructed as in the preceding example ; or otherwise thus , Draw the line AB of any length , and draw AC making the angle A = 53 ° 8 ' ; make AC = 480 by a scale of equal parts , and from C draw CB perpendicular to AB ...

This is constructed in the same manner as the preceding example ; only AB , being shorter than BC , the arc ab cuts AC in two points on the same side of BC ; hence the angle A may be either acute or obtuse . The side required has also ...

The preceding rules solve all the cases of plane triangles , both right - angled and oblique . There are however other rules , suited to right angled triangles , which are sometimes more convenient than the general ones .
