What can and cannot be assumedYou May Assume: You May Not Assume
(unless marked):
Things that look straight are straight.
Exact measurements and relative sizes of figures.Points shown on a line are
collinear. Unless planes are drawn, all points shown are coplanar.
Parallel or perpendicular lines.
Relative position of points are accurate.
