We call these right triangles
OpenStudy (eyust707):
and they are very special becuase we can use thier angles and sides to say all sorts of cool things about the rest of the triangle
OpenStudy (eyust707):
so if i give you an angle of the triangle and one side, you can use math to tell me the length of the two other sides
