A. There are 8 points: A, B, C, D, E, F, G and H
B. There are 9 lines in the figure: AB, BC, AC, DE, DF, EF, BE, AD and CF
C. There are 5 planes in the figure: ABC, DEF, ABED, ACFD and BEFC
D. Three points are collinear if they lie on the same line. Collinear points are D,G and F or C,H and F
E. Coplanar points are those which lie in the same plane. Coplanar points are B, E, F and C or A, C, F and D or A, B, E and D or other combinations of four points lying in the same plane
I. Planes ABC and ABE intersect by a line AB
G. Planes BCH and DEF intersect by a line EF
H. Lines AD and DF intersect at a point D
