Question

Please teach how to put the 4th sum in the clipping

Answer 1

Step-by-step explanation:

1.draw a line segment AB=11cm

2.construct an angle of 30 degree at point A

3.now bisect the angle BAP

4.construct an angle of 90 degree at point B

5. Now bisect the angle ABR

6.lets say these bisect intersect each other at X

7.draw the perpendicular bisector of Bx

8.lets say it intersect AB at Z

9.Now draw the perpendicular bisector of Ax say it intersect AB at y

10.join XY and xZ.
