likeways the angle FCD, the angles CDF 
CFD will be given ; and therefore the an- 
gles BCK, KCF will be given; and there+ 
fore the ares BK, KF are given : Becaufe 
FG is a tangent to the circle at the point 
F, the angle CFG will be a right angle; 
Aind becaufe the angle FCG is given, and 
likeways the fide CF given, the fides CG, 
Ci will be given: In the triangle GCD, 
becaufe the fides GC, GD are given, and 
the angle GCD piven, the angles CGD, 
CDG will be given: And in the triangle 
GCH, becaufe' the fides GC, CH and the 
angle CGH. is given, the angle*GCH will 
be given; and therefore the arc HK will 
be given: And. becaufe the arc PK is gi- 
ven, therefore the arc FH is given. Again, 
becaufe the arc FK is given, the fector 
FCK will be given, and likeways the tri- 
angle FCK given; therefore ‘the {pace 
KEFK will be given; and becaufe the 
‘ triangles GFC, GHC, are given, the fpace 
GFCHG will be given; and becaufe the - 
arc FH is given, the fector FCH will be — 
given; therefore the fpace @FHG.will be 
givens . .
