and

and you know that the measures of these two line segments are the same. Then you can write

which means \"line segment AB is congruent to line segment CD\" or you could write

which means \"the measure of line segment AB is equal to the measure of line segment CD\". However, it would be wrong to say

. In other words the statement \"the line segment AB is equal to the line segment CD\" is nonsense.
