 Hello and how are you all today? My name is Priyanka and the question says construct the angles of the following measurement. Now the second part over here is to construct an angle of 22 1 by 2 degrees. So what we need to do over here is, first of all the first step will be to draw an angle of A O B that is equal to 90 degrees. This angle has been explained to you in the first question. Then the second step will be draw the bisector O C of angle A O B and therefore angle A O C will be equal to 45 degrees. This was your second question explanation and so the required first construction was to draw an angle of A O B equal to 90 degree and then to draw the bisector O C of this angle A O B to form an angle A O C that is equal to 45 degrees. Then draw the bisector of angle A O C such that it will be equal to the two angles will be equal to 22 and a half degrees. So what we will be doing is taking we will be drawing O D as the angle bisector of this 45 degrees so it will be like this. So here we have drawn O D the angle bisector of this 45 degrees. What we did was we took this point as the center drawn an arc then this point as the center drawn another arc intersecting at point D and joined O D. So angle A O D is equal to 22 and a half degrees that is this is the required 22 and a half degrees angle and this is also 22 and a half degrees and this is also 22 and a half degrees as O D is the angle bisector it is bisecting angle A O C into two equal halves. So angle A O D is also 22 and a half and angle D O C is also 22 and a half degrees. So this was our required construction of 22 and a half degrees. So first you should be well versed with the construction of 90 degree then 45 degree and then it will be easier for you to draw the 22 and a half degrees angle. So this completes my session hope you enjoyed and let me write down the final construction step also what we did was we bisected angle A O C such that angle A O D is equal to angle D O C is equal to 22 and a half degrees and therefore our required angle has been drawn. So do not forget to write your steps of construction neatly and bye for now.
