Which statement shows the difference in constructing a pair of parallel lines and a pair of perpendicular lines? A congruent angle is constructed only when constructing a pair of parallel lines and not when constructing a pair of perpendicular lines. A compass is required only when constructing a pair of parallel lines and not when constructing a pair of perpendicular lines. An angle bisector is constructed only when constructing a pair of parallel lines and not when creating a pair of perpendicular lines. Intersecting arcs are formed only when constructing a pair of perpendicular lines and not when constructing a pair of parallel lines.

is that all of it or did it cut you off?

jimthompson5910 (jim_thompson5910):

"A compass is required only when constructing a pair of parallel lines and not when constructing a pair of perpendicular lines. " is completely false since you need a compass for both so choice B is out

jimthompson5910 (jim_thompson5910):

"Intersecting arcs are formed only when constructing a pair of perpendicular lines and not when constructing a pair of parallel lines." is also false. When you use a compass to create the arcs for both, those arcs will intersect (which is the intended point) this means choice D is out

jimthompson5910 (jim_thompson5910):

"An angle bisector is constructed only when constructing a pair of parallel lines and not when creating a pair of perpendicular lines." is false because you don't use an angle bisector (you construct a congruent angle, but not the angle bisector) so C is out

so it's a? thank you for all your help!!
