Question

constract an angle 90°with the help of the compas . biset it and alsowrite its steps​

Answer 1

Answer:

• Draw a straight line AB and an arc on it .
• Place the pointer of compass on the end of the arc B and cut an arc which is of 60 degree ...
• Use the same procedure at point A which makes angle of120 degree..
• Now place the pointer on arc of 60 degree and draw and arc in its left.

Answer 2

Answer:

Step :

We can construct a 90º angle either by bisecting a straight angle or using the following steps.

Step 1:  Draw the arm PA.

Step 2:  Place the point of the compass at P 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 PQ 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 PQ 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 PQ near T as shown.

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

Step 7:  Join T to P. The angle APT is 90º.
