Question

this is soooooo confuuuusiiiiinnnng me​

Answer 1

first make line of your measure
then make an angle of 90degree at any point
after that Make an angle bisector of 90 degree you will get 45 degree and then again draw a angle bisector of that 45degree u will get your 22 1/2 degree as half of 45 is 22.5

Answer 2

Step 1: Draw the arm AB.

Step 2: Place the point of the compass at A and draw an arc that cuts the arm at Q.

Step 3: Place the point of the compass at Q and draw an arc of radius AQ that cuts the arc drawn in Step 2 at R.

Step 4: With the

point of the compass at R, draw an arc of radius AQ to cut the arc drawn in Step 2 at S.

Step 5: With the point of the compass still at R, draw another arc of radius AQ near C as shown.

Step 6: With the point of the compass at S, draw an arc of radius AQ to cut the arc drawn in step 5 at T.

Step 7: Join C to A The angleCAB is 90º.

Step8: With T as center and radius AQ draw an arc.

Step9 : With Q as center and radius AQ draw another arc intersecting the previous arc at D.

Step 10:Join AD.AD is angle bisector of CAB.

Step11:Similarly ,draw angle bisector of BAD.

$And \: finally \: you \: will \: get \: BAE = 22 \frac{1}{2} °$
