# Coordinates of rectangle example

Learn how to sort coordinates from least to greatest using a rectangle diagram. Understand how x, y, and z coordinates relate to each other. Discover that y equals four, z equals three, and x equals two. Master sorting these values in ascending order: x, z, y.

• This is confusing and counter-intuitive but maybe that's a good thing because it forces you to correctly associate the x/y axes with the 2 values in an ordered pair.
I used a, b and c instead of x, y and z to make this easier to understand.
• very confusing indeed
• why does x go first instead of y
• With a coordinate grid, the horizontal direction, or "axis" is called the x axis. The vertical direction, or axis, is called the y axis. In ordered pairs, the things in parentheses that tell you what point it's referring to, the x axis is always the first number, probably because it's first in the alphabet.
• So is this like a number swapping place to place
• How do you find the length of a shape with coordinates.
• Find the distance between two points. So in this video, we end up with (2, 7) and (2, 3). This distance between 3 and 7 is 4, so we know the side between those two points has a length of 4.
• what are the digits of pi?

• Well, pi (π) has infinite non-repeating decimals after the point. So the most common ways to abbreviate are:
- 22/7
- 3.14

Extra digits are: 3.14159265358979323... so on so forth. Most of the time you can just use 3.14.
• why does x go first instead of y
• because it is
