  • - knife, scissors, jigsaws and other cutting tools.
If the surface of the material is quite extensive and allows you to make marks, draw a line slice with a ruler. Then draw a line perpendicular to this line, using the angle ofthe parts or any object with smooth edges, for example, a sheet of paper or a book.
Line mark on each side of the equal angle intervals, for example, 10 cm, Measure the distance between the received points and divide it in half. This point connect with the top angle. You got the angle to 45º, now cut the material on the drawn lines using scissors, knife, jig saw or other tools.
Select one of the lines of the cut, take the protractor and attach to the line. Locate the scale mark 45º and connect this point with the center of the protractor. According to the planned lines cut the material available tools.
Paper, film, foil or other easily flexible material cut in the following way: find or draw a straight angle (for the sheet of paper that any of its corners). Fold the sheet so that adjacent sides match. Cut the paper along the fold line.
If you need to cut the angle of 45 degrees several times, for example, when fitting the plinth, make a template. To do this, take a thick cardboard, draw the square and cut it diagonally.
In order to cut materials at an angle of 45 ° in large volumes, buy a mitre box, this tool can be easily found in any hardware store. Attach the baseboard or the inside rail so as to be located in space, and cut it with a knife, a jigsaw or other tool.
