(01.03 MC) Beau is planning to remodel his shed and is working on the diagram below. He will need to construct a perpendicular through point L to position a pole at a designated point on the floor of his current shed so that the pole is perpendicular to the ground at that point. Which step should he do first to ensure that the resulting pole is perpendicular to the floor at location L?
