Slide 1
4
planes: Planes Y or FGD, EGD, EGF, and EFD
 Points A, B, C are collinear because the all share the
same line
 Points A, G, D, and E (or A or C) are non-coplanar
because E is not in the plane with A, G, and D.
 Line AC

 5+4x+x=180
5+5x=180, x= 35, angles= 35 and 145
 X+3x+10= 90
4x+10=90, x=20, angles = 20 and 70
 90 degrees each
