Landscape has the considerable value on the training of art schools students. The uniqueness of the landscape art is the ability to solve complex graphical, colorful, composite tasks in a simple, understandable form. In the process of training the interest to creative comprehension of provided educational material is stimulating, a stable internal motivation of students to mastering new knowledge is forming. The expediency of using the landscape to form spatial thinking of students of art schools is the main task of training the secondary art institutions specialists. The effectiveness of the

Abstract:
A discussion is presented of the mechanics of the plate-like behaviour of certain space trusses that possess a single layer of chords. The web systems are formed out of the chord plane, and consideration is given to web systems that are placed on one or both sides of the chord plane. It is recognized that a torsional mode of behaviour is utilized for the double-layer web system for carrying transverse load. A combination of flexural and torsional modes is utilized for the single-layer system.

Abstract:
An injection defined from Euclidean space n-space E^n to itself which preserves the triangles of perimeter 1 is an Eucldean motion. J. Lester gave two different proofs for this theorem in Euclidean plane [1] and Euclidean space [2]. In this study a new technique is developed for the proof of this theorem which is valid in both Euclidean plane and Euclidean space.
