Question

Construct an angle of 45 and bisect the angle.​

Answer 1

Step-by-step explanation:

Making 45 degree angle:–

1. First make an semi-circle on a straight line.
2. Then, take the arc of the diameter of semi circle.
3. Then make an angle of 60 degree on the semi circle.
4. Then, Make an angle of 120 degree on the semi circle.

(Making 90 Degree Angle)

1. Then, put the needle of the compass on 60 degree angle where it is touching to the semi circle.
2. And then, cut an arc upside .
3. Then, do the same process on 120 degree angle.
4. (The point which is made by meeting the cut of arc's).(Make a line through this point to the point where all angles are meeting) This angle is of 90 degree.

Now This 90 Degree Angle

1. Put the needle of the compass on the 90 angle where it is touching to the semi circle.Then cut an arc aside.
2. Then put the needle on the starting point of the semi circle and cut to the earlier arc.
3. From this point draw a line to where all angles are meeting.
4. This angle will be of 45 degree.

Bisecting 45 degree angle:–

1. Put the needle of the compass on the 45 degree angle where it is touching to the semi circle. Cut an arc aside.
2. Now, Put the needle of the compass on the starting point of the semi circle and cut an arc to the previous arc. A new point will be formed.
3. Now, draw a line through this point to where all angles are meeting.
4. This angle is the bisector of 45 degree angle.
5. This is 22.5 degree angle.
