... the same height. Explain why the guy wires reach the ground at the same distance from the base of the post. 66. When you open a stepladder, you use a brace on each side of the ladder to lock the legs in place. Explain why the triangles formed on each side by the legs and the ground (∆ABC and ∆DEF in ...

... Sample answer: I constructed a pair of perpendicular segments and then used the same compass setting to mark points equidistant from their intersection. I measured both legs for each triangle. When using the student edition, the measurements are: AB = AC = 1.3 cm, DE = DF = 1.9 cm, and GH = GJ = 2.3 ...
