BC: Today I have found and irregular decagon with 10 sides and vertices and an angle measure of 1440 degrees. It sides aren't the same length but in the end it still has some of the properties the regular decagon has. This is the last shape I will ever discover. I will name this shape the irregular decagon. July 21, 1598

FC: Polygons The Diary of Mr. I. Luv Polygon

1: In my discoveries I have found a regular polygon with 4 sides that seems like the perfect polygon. I shall be calling this polygon the square. It seems this polygon has 4 vertices and has a total angle sum measuring up to 360 degrees. December 10, 1595

2: After days of experimenting with the square I have found out that you could turn it into a different type of Quadrilateral, the rectangle. The rectangle has 4 sides and vertices and once again has an angle sum of 360 degrees. However, it doesn't have all of it's sides the same length which means it is irregular. January 3, 1596

3: While my mother was making a cloth, I have found a shape that has 4 sides with the same length and 4 vertices. It also has 2 pairs of congruent lines and has a total angle measure of 360 degrees. It does however, has different angle measures for the individual angles alone. Because of it's difference in a certain property, I will be naming this irregular polygon the rhombus January 11, 1596

4: I have found a very different looking quadrilateral which has different angle measures for it's individual vertices and has only one pair of congruent lines. It still does however, have a total angle measure of 360 degrees. It seems silly to still point this out but it has 4 sides and vertices. This polygons shall be known as the trapezoid. March 4, 1596

5: Upon searching for new shapes I have found a polygon with 3 sides and vertices. All of this polygons sides are the same length with an angle measure totaling up to 180 degrees. This polygon shall be known as the acute triangle. April 2, 1596

6: Upon studying the acute triangle or now known as equilateral triangle, I have found that when changing the length of a triangles sides, if two of those sides are the same length it can be a triangle with 3 sides and vertices, it can have a total angle measure of 180 degrees, but only two of the sides in the triangle are the same length. This polygon shall be known as the isosceles triangle. April 6, 1596

7: Today I wondered if there could be a triangle with one right angle. I was right. I have found a new triangle with a total angle measure of 180 degrees and 3 sides and vertices. It has one right angle and two acute angles. This triangle was named right triangle, for the right angle it has. April 29, 1596

8: Today I tried to stop my research with triangles and tried to find one more type of triangle. The triangle I found today had on obtuse and two acute angles. It has 3 sides and vertices like any other triangle and had a total angle measure of 180 degrees. I have named the triangle the scalene triangle. May 1, 1596

9: I wondered today if there were to be a polygon with 5 sides and vertices and have a total angle measure of 540 degrees. It seems that I was lucky for I have found this shape while my mother was making a cloth. I have named this shape the pentagon. May 12, 1596

10: Today while looking at jewelery with my mother I found a pentagon still with 5 sides and vertices and a total angle measure of 540 degrees, but it was and irregular pentagon with sides that were not congruent to each other. This shape will be known as an irregular pentagon. May 14, 1596

11: Thank my lucky soul for today I have found a polygon with 6 sides and vertices. this polygon has a total angle measure of this polygon is 720 degrees and it is a regular polygon having all of it's sides congruent to each other. This polygon shall be known as the hexagon. June 3, 1596

12: Today I found a peculiar shape with 6 sides and vertices like the hexagon and a total angle measure of 720 degrees. This odd shape is shaped like a L and doesn't have congruent sides like the regular hexagon. I will be naming this shape the irregular hexagon. February 7, 1597

13: Today I found a shape with 8 sides and vertices with a total angle measure of 1080 degrees. All of it's sides are congruent and it has only obtuse angles. This shape shall be known as the octagon. December 21, 1597

14: While looking at gems I found a shape with 8 sides and vertices with a total angle measure of 1080 degrees. This polygon has different lengths for it's sides and has 2 pairs of parallel lines. This shape will be named the irregular octagon. January 9, 1598

15: Today I found a shape with 10 sides and vertices and a total angle measure of 1440 degrees. All of it's sides were the same length so it is a regular polygon. This shape was named the Decagon. March 7, 1598
