A chord is the part of a circle defined by two endpoints.
An angle has two endpoints and a single vertex.
To find the length of a side, you either measure it, or you calculate it. How you calculate it depends on what data is given. For example, if you have the coordinates of the endpoints of a line, you can calculate the length by using the Pythagorean theorem (or simply subtracting the coordinates of the two endpoints, if the line is perfectly vertical or perfectly horizontal).

endpoints!! endpoints!!

A line segment connects two endpoints.
the two endpoints of a line make a line segment. endpoints are just endpoints

To get the midpoint between two points, the x-coordinate of the resulting point is the average of the x-coordinates of your two points. Similar for the y-coordinate. Take the average of the endpoints, calculate the average of the x-coordinates.
Put the numbers in order. The odd one in the middle is the median: 1,2,3,4,5,6,7 (4 is the median). If even numbers, it is between the two middle numbers: 1,2,3,4,5,6,7,8 (between 4 and 5 is the median).
