1 00:00:00,430 --> 00:00:08,589 Let's make a regular heptagon that is quite similar to the pentagon, but much more easier, okay? 2 00:00:08,970 --> 00:00:17,589 So, the first thing that we have to do, as we always do, is to draw a diameter, okay? 3 00:00:18,309 --> 00:00:18,829 That's it. 4 00:00:19,170 --> 00:00:20,789 Here we have a diameter, okay? 5 00:00:21,109 --> 00:00:22,109 A, B. 6 00:00:22,969 --> 00:00:27,949 And now, we are going to draw the bisector line of this radius, okay? 7 00:00:28,510 --> 00:00:29,609 Radius OB. 8 00:00:29,609 --> 00:00:34,609 Do you remember that we did it here in the pentagon? 9 00:00:34,609 --> 00:00:37,609 Now we are going to do it down below. 10 00:00:37,609 --> 00:00:51,609 So we place the needle in B and the pencil in O and we draw an arch. 11 00:00:51,609 --> 00:00:56,609 Well, it's also the same thing we have done with the triangle. 12 00:00:56,609 --> 00:01:19,540 Now, we have another two points, C and D, okay, and this, okay, this, this is going to be M, okay, this is the middle point between O and E, or also the middle point between C and D, okay. 13 00:01:19,540 --> 00:01:25,719 Okay, cm is the length of the side of the heptagon, okay? 14 00:01:26,019 --> 00:01:29,739 Hepta means seven in Greek, okay? 15 00:01:30,060 --> 00:01:40,500 So what we are going to do is to take this measure and from A, okay, you can do it wherever you want, okay? 16 00:01:40,579 --> 00:01:45,019 From A, from C, from B, from any point of the circumference, okay? 17 00:01:45,079 --> 00:01:46,780 But we are going to do it quite organized. 18 00:01:46,780 --> 00:01:58,280 it we're going to put place here one point and another point okay here okay 19 00:01:58,280 --> 00:02:11,800 and here okay one two three four five six and seven and if we have done it 20 00:02:11,800 --> 00:02:17,819 properly this distance must, between these two points, must be the same length. 21 00:02:17,819 --> 00:02:34,900 Okay, that's correct. Okay, so we have that A is also a point 1, 2, 3, 4, 5, 6 and 7. 22 00:02:34,900 --> 00:02:40,900 And if we join the points we will obtain the heptagon. Let's make a 23 00:02:40,900 --> 00:02:45,300 regular here we have it
