SOLVING TRIANGLES 

1.  C = _________
2.  D = _________
3.  E = _________

The Following problem will probably be one of the most frequent trig problems that you will encounter while developing flat patterns with acute bend angles (See Acute Bends Page:40). You will have to use this problem when a dimension is given to the center of a radius or if it is dimensioned tangent to the outside of the material. The "A" dimension is one necessary for development. The formula is the same for acute and obtuse angles.

C bisects rays a & b
Rays a & b are tangent to circle

4.  B = _________
5.  D = _________
6.  A = _________
7.  C = _________
8.  E = _________
