So in this lesson, we're going to take a closer look at the two primary shapes that we use in garden design. And these are the circle and the square. And they both have component parts to them. So we're gonna look at how these components not only define the original shape, but also how you use them to combine these two shapes to create really strong designs, and really strong form composition. So let's start with a circle. The center is the most arguably important point, everything radiates outwards from the center, and the circumference, the radius is defined by it.
All of these components relate directly to the center. So the circumference relates simply to continue arc all the way around the circle. And the circle can be dissected in half by the diameter. And then of course, we have the radius which is Basically half of the circle or the diameter, and there is one last line that we have related to circle, and that is tangent which is an outside line from any point of the arc of the circle, all the lines can also be extended. So here are all the component parts of the circle. So let's look at the square now.
As everyone knows, a square is basically a box with four equal sides, and it can be dissected in half on its axis. And now we have four proportionally same squares square can be all well divided on the diagonal. So we have 45 degree angle, all the lines in square can also be extended. And also the smallest squares inside of the square can be divided. So these are all the components of the square which can be used to build a strong composition strong form for design. So let's have a look at this example.
Looking at the patio, you can extend the top line, it flows effortlessly into the tangent of the circle swings around on the arc of the circumference. If the two lines were extended, they would need right in the center of the circle, the water feature so we have an extended radius, even if you don't physically see the lines connecting. Then we have the seating area here with the firepit which is basically double the size of the patio and then the lawn area. And on top, there is nothing at the moment, we can throw in some mass planting. And at this point, it is a conceptual design. I don't really necessarily need to know what kind of materials and plants we are using.
So this is a very simple diagram of how the component parts of shapes relate to each other within the garden design. Up next we're gonna look at some actual designs and how form company position and component parts of shapes work together.
