Question

construct a right angle and draw its bisector.

Answer 1

the right angle is 90 degree and when we bisect the right angle and the bisector angle is 45 degree

Answer 2

Edit: This is not the complete picture, it was uploaded by mistake.

1) Draw a line

2) Draw an arc of any radius as shown.

3) From the end points of the arc construct the perpendicular bisector of the line drawn.

5) This gives us 90°

6) Now adjust the compass to the previous radius.

7) Without disturbing the compass keep it on the point where the arc cuts out base line and make another arc.

8) Now from the point where our arc cuts the normal (90° angle) make another arc cutting the previous one.

9) Join the centre and the arc.

10) You're Done :)
