Back to Lines are taken to lines, and line segments to line segments of the same length — Problem 2 · Task Set 19
Exercises: Rigid Motions Preserve Lines and Lengths
Work through each section in order. For length calculations, use the distance formula $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$. Show your work where indicated.
