Basic Design : Exercise5 Rhythm

Given:
11 square elements
9 rectangle elements
17 isosceles right triangles
The dimentions of these elements should be multiples of 4.5 cm

i made two different groups.The groups consist of rectangle and triangles and the other group includes squares in two different sizes.To represent the concept of rhythm, i decide to show a rhythm in elements of groups as they show move and some how they orbit.Trend of systematic change in size in groups(decrease , increase, decrease,...)is witnessed.Also the number of triangles follow a sequence (5,3,1)

Basic Design: Exercise3

given:
9 planar elements of 9*9
5 rectangle elements of 9*13.5
7 isosceles elements triangles with sides length 9cm

first, i make a group that includes one triangle and two squares or two rectangles, I tried to use this group in differnt dirctions ; horizontally, vertically, ... .

Basic Design:Exercise4

5 planar elements of 9*9cm
7 rectangle elements of 9*13.5cm
4 isosceles  right triangle with sides length 9cm
9 equilateral parallelograms with an 45* angle and a side of 9cm

As we were given parallelograms and triangles , I decided to change the direction of it and actually make angled system.I based the whole system on 45* and 135* and try to parallel the elements in these two angles.By the way i group the elements. my group consists of a parallelogram and a rectangle and a square. rectangle and square are paralle with each other and both of them are parallel with two sides of parallelogram.
