In coordinate geometry you describe a point by an ordered pair (//x,y//), called the //coordinates of the point.// Find out more about coordinate points here: []. You may remember seeing coordinates on a map, such as the treasure map used in this video: [].

Before we go further, test yourself using the //Hard// questions on the following at [].



The Native Americans made intricate bead works that are known for their beauty. Using this software, you will simulate traditional loom designs, and create new virtual designs of your own.

Remember that you can use the Ruler Postulate to find the distance between two points if the points are on a horizontal or vertical line. To find the distance between two points that are on a slanted line, you can use the //Distance Formula,// which is explained here: []

Let's explore a bit more into the Distance Formula and also learn about the //Midpoint Formula:// [].
