And see how far it has turned relative to the left-hand end of the strip. Since we were so careful in laying out the left-hand end of the strip, our task in reckoning the angle of the right-hand end of the strip amounts to deciding what time you get if you think of the right-hand end of the strip as the big hand of a clock. The curvature inside the region will correspond to the amount by which the time told by the right-hand end of the strip falls short of 1 00. For instance, say the region is a

Not Knot is a guided tour into computer-animated hyperbolic space. It proceeds from the world of knots to their complementary spaces -- what& ,s not a knot. Profound theorems of recent mathematics show that most known complements carry the structure of hyperbolic geometry, a geometry in which the sum of three angles of a triangle always is less than 180 degrees. Audience Anyone with an interest in mathematics. Children and teenagers are attracted by the graphics and the narration, while advanced

Also, ensure that D and C lie on opposite sides of the line segment AB. Draw the segment CD. The segments AB and CD intersect at P. AP is the required partition. Length AP = (1 n) length AB..See Figure 1. Triangles CAP and DBP are similar, because Angle A = angle B = 90 by construction Angle APC = angleBPD, vertically opposite angles.The ratio CA BD is
