Abstract:
This article discusses Napoleon’s outer and Napoleon’s inner in general on triangle.
Each vertex is connected from a triangle which is built based on the sides of the
original triangle, so that a new triangle is formed, namely Napoleon’s outer and
Napoleon’s inner with certain conditions. The proof is done using the concept of
similarity. This article is a modification of the Napoleon’s theorem which is applied
by connecting the vertices of the triangle constructed on the side of the original
triangle.
