How to Drawing Pentagon with an Unscaled Ruler and Compass (Accurate Method 2)

Hey, everyone! In this tutorial, I'll guide you through the steps of drawing an Inscribed Regular Pentagon using just an unscaled ruler and a compass. Let's dive in:
Here's what you'll need:
- Unscaled ruler
- Compass
- Pencil
Step-by-step instructions:
1. Mark a point at any location, labeled as O.
2. With O as the center, use any radius to draw a circle.
3. Draw a straight line through O, intersecting the circle at points A and G.
4. With A and G as centers, draw circular arcs greater than AO in radius.
5. Connect the intersection points of the two arcs to create the line AG; this is the perpendicular bisector of AG.
6. Mark the two intersection points on circle O as F and H.
7. With H as the center and OH as the radius, draw a circular arc intersecting circle O at two points.
8. Connect these two points to obtain the perpendicular bisector of OH.
9. Mark the center point of OH as I.
10. With I as the center and IO as the radius, draw a circle.
11. Connect I and G with a straight line.
12. Mark the two intersection points on circle O as J and K.
13. With G as the center and GK as the radius, draw a circular arc.
14. With G as the center and GJ as the radius, draw another circular arc.
15. Mark the intersection points on circle O as B, C, D, and E.
16. Connect AB, BC, CD, DE, and EA to form an inscribed regular pentagon within circle O.
Note:
This pentagon is a regular pentagon, and the theoretical angles based on this method are: ∠DEA = ∠EAB = ∠ABC = ∠BCD = ∠CDE = 108°.
The actual precision of the drawing depends on your accuracy in the actual drawing process.
Thanks for watching!

Magic! I just looked up and found out the interior angles are 108°. How this process can produce an angle which is 0.3 of 360° is a complete mystery to me.
