Question

How to construct 45 degree ..help me guys​

Answer 1

if you have to construct with protractor then take a protractor and draw a straight line and set mid point of protractor at the center of line and draw a straight line to 45 degree by using pencil.

Answer 2

1) Make perpendicular lines(elbows at 0 points)

2) then put the term needle at point 0 and open the term with the size up( not too big)

3)turn the term. so that the bow we make cuts a line that is perpendicular to each other(in the picture shown on a red bow intersecting points A and B)

4)put, needle at point A them turn the run

5)put the term at point B, then rotate term until it intersects with the round term centered at point A

6)in the picture is a green bow

7) pull the intersection line to point 0(elbow point) so that an angle of 45 degress is formed
