Question

geometric definitions
three students attempt to define what it means for two lines to be parallel.
can you match the teachers comments to the definitions?
definition of parallel lines\tteachers comments
danielas definition: two lines are parallel if one can be translated on top of the other.\tsorry, your definition is incorrect.
oris definition: two lines are parallel if they are close together but dont intersect.\tpart of your definition is correct, but the other part is not. parallel lines dont have to be close together.
kaoris definition: two lines are parallel as long as they arent perpendicular lines.\tnice definition! hip, hip, hurrah!

Explanation:

Daniela's definition is incorrect because just being able to translate one line on top of the other could mean they are the same line, not necessarily parallel. Ori's definition has a wrong - part as parallel lines can be far apart, not just close together while not intersecting. Kaori's definition is wrong as non - perpendicular lines can still intersect and not be parallel. The correct definition of parallel lines is that they are coplanar lines that do not intersect.

Answer:

Daniela's definition matches "Sorry, your definition is incorrect."; Ori's definition matches "Part of your definition is correct, but the other part is not. Parallel lines don't have to be close together."; Kaori's definition matches "Sorry, your definition is incorrect."
