Pentagon with 2 external diagonals

A pentagon is not necessarily one of the common figures in mathematics, they just form a separate group from circles and squares. When it comes to drawing a copy with 2 external diagonals, the fun stops completely for many students. The technical terms sound confusing and drawing seems impossible. If you feel the same way, you simply need some information about the figure mentioned, and you will surely have a better perspective than before.

What a pentagon is should be obvious at first glance, but not every figure has a 2 external diagonals, which means that you cannot tell the teacher every drawing submit. Such a corner is sure to be drawn quickly, but then it is not always certain whether you really are meet the requirements, namely, it depends on the shape of the figure through which you the position the Straight lines determine.

The pentagon in mathematics - explanation

It is a figure that belongs to the polygons, the so-called "polygons". You may have heard of the term "Pentagon" - this is nothing more than a regular, that is, symmetrical figure. As beautiful as this drawing looks with its sides of the same length, you will only find straight lines within the figure, the corner must be irregular for the outer parts.

Figure with 2 external diagonals - worth knowing

  • It is of course important here that you do not lose sight of the basic structure. The number of corners must be exactly five, no more and no less, at the same time there is a constant number of pages, which is also five.
  • Diagonals are always the connections that can be drawn between two corners, so a square generally only has two diagonal connections. It is important that these points are not directly next to each other, otherwise you will only draw one of the boundary lines and you would not be able to distinguish between inside and outside.
  • The straight lines mentioned are not just called that, they actually have to lie outside the figure. This does not have to be done entirely, but at best these lines are really on the outside as a whole.
  • Calculate the diagonal - this is how it works with the cuboid

    In school, you need to calculate the diagonals of different bodies. Here …

  • Drawing may be a challenge at first, but if you stick to the features mentioned, this process shouldn't be that difficult at all. Prepare yourself a coordinate system, an x-axis and a y-axis are completely sufficient, negative values ​​are not required. Now mark the points "A = 0; 0, B = 1; 5, C = 1.5; 1.5, D = 2.5; 1.5 and E = 3.5; 1" (the first Number always refers to the x-value, the other to Y, the designations help to keep the Overview). Drag the connections in sequence so that you can see the finished figure. With a lot of imagination you now have a boomerang in front of you. The correct straight lines can be found on corners B to D and from B to E. You can draw the lines once to determine the correctness yourself.

As you can see, drawing a pentagon with two external diagonals is not as difficult as it was initially thought. The only hurdle is the correct positioning of the figure, you have to think about it a little and maybe even try it out.
