Question

Draw a line segment ab of length 5 cm at A and B construct perpendicular to a b also draw the perpendicular bisector of Ab are three lines parallel to each other justify your answer​

Answer 1

So we will follow the following steps for that:

Step 1: Draw a line segment AB of 5 cm with the help of the scale. As shown in the figure below:





Step 2: Now, with the help of the compass with more than 2.5 cm and draw two circles of the same radius centered at A and B. As shown in the figure below:





Step 3: Now these two circles will intersects at two points, let it be C and D. Next, draw the line between C and D. As shown in the figure below:





Finally the line CD is the perpendicular bisector of the line segment AB.

Note: It is important that we draw the two circles that should be of the same radius. And take the radius after measuring the length of the line segment. The name perpendicular bisector is because then two lines are intersecting at 90 degrees.
