Here, degrees =de.

these are the steps to draw an angle of 45de. :-

1.Draw a line AB.

2.Keep the point of the compass at A and draw an arc cutting AB at C.

3.Keep the point of the compass at C and draw an arc cutting the previos arc at D.

4.Keep the point of the compass at D and draw an arc cutting the previous arc at E.

5.Keep the point of the compass at E and draw an arc wherever you feel suitable for drawing a right angle.

6.Keep the point of the compass at Dand draw an arc cutting the arc which you drew for constructing the right triangle at F.

7.Draw a line from A to F. You will get a straight line which will be your right angle.

8.You will get a point between A and F. Name the point G.
