Circles that have congruent radii. Congruent=coinciding at all points when superimposed (http://dictionary.reference.com/browse/congruent)
Different types of lines are :parallel lines, intersecting lines, perpendicular lines,oblique lines, vertical lines, horizontal lines, zigzag lines, curved lines ,wavy lines, and dashed or dotted lines.
Either parallel lines or longitudinal lines are opposite transversal lines.
40 lines.40 lines.40 lines.40 lines.
No. Skew lines are lines in different planes that are parallel.
Parallel or coinciding. Coinciding may not be a good answer in some cases but parallel is safe to say.
no solutions
Lines with equal slopes are parallel, because they are going the same direction. If the slope and the intercept are the same, the lines are coinciding, because they are on top of each other.
They are coinciding which means they have an infinite number of solutions.
Congruence.
Identicle in form; coinciding exactly when superimposed
