This thesis discusses the arithmetic alternatives to pentagonal fuzzy numbers. The discussion begins with the definition of the positivity of pentagonal fuzzy numbers which is constructed using a ratio of areas in the positive r-axis and negative r-axes (in the first quadrant and the second quadrant). Then, from the concept of positivity fuzzy numbers, an alternative arithmetic fo…
This thesis discusses the subalgebra and ideal concepts in companion BN1- algebra which are called companion sub BN1-algebra and companion BN1-ideal. Let S is a nonempty subset of X . S is said to be a subalgebra of X , if x, y ∈ S, then x ∗ y ∈ S. While S is called ideal of X , if x ∗ y, y ∈ S, then x ∈ S. The final result of this research is the properties of companion sub BN1-a…
In general, a lot of discussion of dividing line discusses the angle bisector. This thesis discussed the angle trisector (a line that divides an angle into three equal parts). The discussing is about the side lengths of the angular trisector and the ratio of the area of the corner trisector formed from each corner of the triangle and rectanguler. The proof is done using a very simple method, na…
This thesis discusses the modification Varignon theorem on triangle with dividing the sides of the triangle into thirds, four and five parts and determining general formula if the side of the triangle is divided into n parts. The proving process is done in a simple way, namely by using the similarity between two triangles, the sine rule, the cosine rule and the sequence of numbers.The result is…
This thesis discusses the Nagel point triangle in the modified Napoleon theorem, that is if each side of the outside of an original triangle is built, each is an isosceles triangle with a height twice the height of the equilateral triangle. The nagel points of the three outer isosceles triangles will form a new triangle corresponding to the original triangle. This means that if the original tri…
This thesis discusses the algebraical development of fully trapezoidal fuzzy numbers by rst dening positive and negative fuzzy numbers. Next a solution of fully trapezoidal fuzzy numbers is obtained using the inverse matrix of numbers that have been determined in advance. This development provides the compatible results.
