Let’s take the example of this triangle shown here. In this case, all three coordinates of this triangle are labeled as point A, B, and C:

We will make this triangle in the following example using the Line command, but instead of direct distances, we will use coordinate values:

1. Select the Line tool from the Draw panel or use its command alias, L, to start the command.
2. The command line will prompt you to specify the first point for the line, as in figure 2.5. Type 0,0 for the first coordinate point, which is also the A point of the triangle, and press Enter.
3. Now, we need to specify the coordinates of the second point, B. Type 10,0 and press Enter again. The cursor will move to the B point of the triangle.
4. Once again, we need to specify the coordinates of the next point, C. So, type 14,7 and press Enter.
5. Now, our cursor is at the C point and you can simply type 0,0 and press Enter to return to the first point, which is the origin. To exit the command, press the Enter or Esc key once.

As you have noticed, we only required the coordinates to make this triangle, but the coordinates are rarely used for making drawings and, in most cases, the length and angle values are predominantly used. In real-world drawings too, we will use direct distance entry primarily, but there will be a few instances where coordinates will also be used to make drawings.

In the next example, we will learn how to make a simple drawing using the polar coordinate system.
