length
It could be the diameter of a circle that produces 2 congruent segments or the midpoint of a line segment
It could be any number of polygons with 4 or more sides.
That the two segments are equal.
congruent segments are the same segments.
Line segments are congruent if they have the same length.
Two angles are congruent if they both measure exactly the same number of degrees. Two line segments are congruent if they both have exactly the same length.
When they have the same chord lengths
congruent line segments- line segments that have the same lengths.
They are congruent.
Line segments are congruent if they have the same length
Congruent Segments (sides) : Segments that are of the same lengths.
First, lines and rays cannot be congruent because they do not have both end points defined. Not having an end point define means we cannot talk about their length so they can't be congruent. Line segments, however, can be congruent. Congruent line segments NEED NOT be parallel.Furthermore, if two line segments are parallel, that does not mean they are congruent since parallel line segments may not have the same length.Congruent line segments would be ones that are the same length.
midpoint
If by "equal" you mean "equal in length", yes, that is the same as "congruent".
