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?
(1 vote)
• 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
• this video has nothing to do with the quizes and assignments
• Someone please comment if you don't understand and/or if I'm wrong:

There are two versions of this problem: Rectangle and Parallelograms

Step by step for finding Rectangle coordinates:

1. You first check if the variable is an “X” or “Y” coordinate. For example: In (a, 2), "a" is the X coordinate. In (4, d), "d" is is the Y coordinate.
2. Check the coordinate that is BELOW or ABOVE the variable you're searching for. If there's a rectangle and (a, 2) is ABOVE of the coordinate (10, 5), then a = 10. If (4, d) is BELOW of the coordinate (10, 20) then d = 20.
3. Compare variable values from greatest to least.

Step by step for finding Parallelograms coordinates:

1. Repeat the first step from the RECTANGLE by identifying if the variables are "X" or "Y" coordinates.
2. To find the value of the variable that is a "X" coordinate, you search for the "X" value that is on the DIAGONAL OPPOSITE SIDE. Example: If the variable that is an “X” coordinate is located on the TOP RIGHT of the parallelogram, then the correct coordinate would be on the BOTTOM LEFT.
3. If the variable is a “Y” coordinate like for example (10, d), then you find the “Y” coordinate value that is HORIZONTALLY ON THE OPPOSITE SIDE.
4. Compare variable values from greatest to least.
