*can you construct***HOW***using straight edge and compass only*, an - isosceles triangle - isosceles right triangle - equilateral triangle with one vertex on each line? Does your construction work for any set of three parallel lines?**Use the blue dots to set the positions of the parallel lines Use the green dots to position the vertices of the triangle**
