ruler and compass​

Answer 1

..Steps..

We can construct a 90° angle either boy Biseeting a straight angle or using the following steps.

Step 1: Draw the arm PA.

Step 1: Draw the arm PA.Step 2: Place the point of the

Step 1: Draw the arm PA.Step 2: Place the point of thecompass at P and draw an arc thatcuts the arm at Q.

Step 1: Draw the arm PA.Step 2: Place the point of thecompass at P and draw an arc thatcuts the arm at Q.Step 3: Place the point of the compass at Q and draw an arc of

Step 1: Draw the arm PA.Step 2: Place the point of thecompass at P and draw an arc thatcuts the arm at Q.Step 3: Place the point of the compass at Q and draw an arc ofradius PQ that cuts the arc drawn in

Step 1: Draw the arm PA.Step 2: Place the point of thecompass at P and draw an arc thatcuts the arm at Q.Step 3: Place the point of the compass at Q and draw an arc ofradius PQ that cuts the arc drawn inStep 2 at R.

Step 1: Draw the arm PA.Step 2: Place the point of thecompass at P and draw an arc thatcuts the arm at Q.Step 3: Place the point of the compass at Q and draw an arc ofradius PQ that cuts the arc drawn inStep 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.

S.Step 5: With the point of the compass still at R, draw another arc of radius PQ near 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.

S.Step 5: With the point of the compass still at R, draw another arc of radius PQ near 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 90°.
