Question

26. Construct 45° without using protractor.
​

Answer 1

Answer:

construct 45 degree angle, first we draw 90 degree angle and its done in the following steps:

1). Use ruler and draw a Line segment OB of any convenient length. (as shown below)

2). Now use compass and open it to any convenient radius. And with O as center , draw an arc which cuts line segment OB at X . (as shown below)

3). Again use compass and opened to the same radius (as of step 2). And with X as center , draw an arc which cuts first arc at D . (as shown below)

4). Again use compass and opened to the same radius (as of step 2). And with D as center , draw another arc which cuts first arc at C . (as shown below)

5). Again use compass and opened to the same radius (as of step 2). And With C & D as center , draw two arcs which cuts each other at E . (as shown below)

6). Join OE and extent it to A . (as shown below)

7). Above formed angle AOB = 90 Degree

Now, to construct at 45 degree angle, we will construct the angle bisector of above angle AOB. And its done in the following steps:

8). Again use compass and open it to any convenient radius. And with O as center , draw an arc which cuts line segment OB at P and OA at Q . (as shown below)

9) Again use compass and opened to same radius (as of step 8).And with P & Q as center and, draw two arcs which cuts each other at point F. (as shown below)

10) Join OF and extend to E. (as shown below)
