What do we mean when we say that two line segments are congruent

This concept indicates that two line segments have the same length.

Explanation:

This concept indicates that two line segments have the same length. The position and orientation of the segments may be totally different and the segments will still be congruent as long as they ahve the same length.

Two line segments are congruent if they have the same length. They do not need to have the same position or orientation.

Step-by-step explanation:

To find the number of notebooks Steve bought you will subtract the amount he paid for his backpack from the total amount, and then you will divide the remaining amount by $3.98 to find the number of notebooks.

($43.78 - $27.86)/$3.98
$15.92/$3.98
4

Steve bought 4 notebooks.
