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.\tpart of your definition is correct, but the other part is not. parallel lines dont have to be close together.
oris definition: two lines are parallel if they are close together but dont intersect.\tsorry, your definition is incorrect.
kaoris definition: two lines are parallel as long as they arent perpendicular.\tnice definition! hip, hip, hurrah!

Explanation:

Daniela's definition has a correct idea about translation but wrongly implies closeness is a requirement. Ori's definition is wrong as closeness is not a criterion for parallel lines. Kaori's definition is wrong because non - perpendicular lines can still intersect and not be parallel. The correct concept of parallel lines is that they are in the same plane and never intersect regardless of distance.

Answer:

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