Correction to: Chapter 1 in: E. Grigorieva,Methods of Solving Complex Geometry Problems, https://doi.org/10.1007/978-3-319-00705-2_1

The book was inadvertently published with an incorrect figure and equation and this has now been corrected.

  1. a)

    Figure 1.29

    figure afigure a
  2. b)

    Equation in problem 2 as

    $$ {\displaystyle \begin{array}{c} AB+ BC= AB+ BE+ EC\\ {}=\left( AB+ BE\right)+ EC> AE+ EC\\ {} AE+ EC=\left( AD+ DE\right)+ EC\\ {}= AD+\left( DE+ EC\right)> AD+ DC.\end{array}} $$
