Updates to Chapter 12, "Decagons and Decagrams",
in Ernest Irving Freese's Geometric Transformations: the Man, the Manuscript, the Magnificent Dissections!,
by Greg N. Frederickson

Capsized by captions!

The captions for Figures I109a, I109b, I110a and I110b are annoyingly imprecise.
For Figures I109a and I109b, replace "two squares" by "two squares of areas 2 and 3".
For Figures I110a and I110b, replace "four squares" by "four squares of areas 1, 2, 3, and 4".
