The Isosceles Trapezoid and its Dissecting Similar Triangles
نویسندگان
چکیده
Isosceles trapezoids are dissected into three similar triangles and rearranged to form two additional isosceles trapezoids. Moreover, triangle centers, one from each similar triangle, form the vertices of a centric triangle which has special properties. For example, the centroidal triangles are congruent to each other and have an area one-ninth of the area of the trapezoids; whereas, the circumcentric triangles are not congruent, but still have equal areas.

Spherical f-tilings by scalene triangles and isosceles trapezoids, I
The study of the dihedral f-tilings of the sphere S whose prototiles are an equilateral or isosceles triangle and an isosceles trapezoid was described in [6]. In this paper we generalize this classification presenting the study of all dihedral spherical f-tilings by scalene triangles and isosceles trapezoids in some cases of adjacency.

The study of the dihedral f-tilings of the sphere S2 whose prototiles are a scalene triangle and an isosceles trapezoid was initiated in [7, 8]. In this paper we complete this classification presenting the study of all dihedral spherical f-tilings by scalene triangles and isosceles trapezoids in the remaining case of adjacency. A list containing all the f-tilings obtained in this paper is prese...
متن کاملSpherical Folding Tessellations by Kites and Isosceles Triangles Ii
Abstract: The classification of the dihedral folding tessellations of the sphere and the plane whose prototiles are a kite and an equilateral triangle were obtained in a recent paper, [1]. Concerning to isosceles triangles the classification is much harder, which is not surprising since more angles are involved. In this paper we extend this classification presenting all the dihedral folding tes...
متن کاملUnderstanding the Eigenstructure of Various Triangles
We examine the eigenstructure of generalized isosceles triangles and explore the possibilities of analytic solutions to the general eigenvalue problem in other triangles. Starting with work based off of Brian McCartin’s paper on equilateral triangles, we first explore the existence of analytic solutions within the space of all isosceles triangles. We find that this method only leads to consiste...
متن کاملOn Isosceles Triangles and Related Problems in a Convex Polygon
Given any convex n-gon, in this article, we: (i) prove that its vertices can form at most n2/2 + Θ(n log n) isosceles trianges with two sides of unit length and show that this bound is optimal in the first order, (ii) conjecture that its vertices can form at most 3n2/4 + o(n2) isosceles triangles and prove this conjecture for a special group of convex n-gons, (iii) prove that its vertices can f...
