Jun 27, 1999 · If we start with two straight line segments with a common endpoint, and then add squiggly parts onto the ends of each one, would we say that the angle has changed as a result? Likewise, look at the angle formed at the lower-left-hand corner of this piece of paper. Even first grade students will recognize this as an example of an angle.
First, generally, "lines" cannot be described as congruent because they have no definite length, so I think you are describing line segments. Line segments are congruent if their lengths are equal. Second, I think there is information in your picture that is not being conveyed in the text of the question.
