A prism is a three-dimensional figure, a polyhedron, the types of which are many: regular and irregular, straight and oblique. According to the figure lying at the base, the prism is from triangular to polygonal. The easiest way is to make a straight prism, but above the inclined one you need to work a little more.
It is necessary
- - compasses;
- - ruler;
- - pencil;
- - scissors;
- - glue;
- - paper or cardboard.
Instructions
Step 1
Draw the bases of the prism, in this case they will be 2 hexagons. Use a compass to draw a regular hexagon. Draw a circle for them, and using the same radius, divide the circle into six parts (for a regular hexagon, the sides are equal to the radius of the circumscribed circle). The resulting figure resembles a honeycomb cell. Draw the irregular hexagon freely, but using a ruler.
Step 2
Now start designing the pattern. The walls of the prism are parallelograms and you need to draw them. In a straight model, a parallelogram is a simple rectangle. And its width will always be equal to the side of the hexagon lying at the base of the prism. With a correct figure at the base, all the faces of the prism will be equal to each other. If it is wrong, each side of the hexagon will correspond to only one parallelogram (one side face), suitable in size. At the same time, follow the sequence of the dimensions of the faces.
Step 3
On a horizontal line, successively mark 6 line segments equal to the side of the base of the hexagon. From the points obtained, draw perpendicular lines of the desired height. Connect the ends of the perpendiculars with a second horizontal line. You now have 6 rectangles joined together.
Step 4
Attach the 2 hexagons constructed earlier to the bottom and top side of one of the rectangles. To any base if it is correct, and to the corresponding length if the hexagon is incorrect. Outline the path with a solid line, and the fold lines inside the shape with a dashed line. You now have a surface scan of a straight prism.
Step 5
Leave the base the same to create a tilted prism. Draw a parallelogram side that will be one of the faces. There should be six such faces, as you remember. To now draw a sweep of an inclined prism, you need to arrange six parallelograms in the following order: three in ascending order, so that their oblique sides form one line, then three in descending order with the same condition. The slope of the resulting line is directly proportional to the tilt of the prism.
Step 6
Draw small trapezoidal overlaps on the short sides to glue the shape to the five rectangles in the flat pattern, and also on one free long side. Cut the blank for the prism with overlaps and glue the model.
