Question

1. Construct AB=7 cm. Mark a point Con AB such that AC=5 cm. Measure the length of the
line segment CB. Also, verify that AC+CB = AB.

2 . Given below are two line segments AB and CD.

(a)Construct PQ such that PQ = AB+CD.

(b)Construct RS such that PQ = AB-CD.​

Answer 1

Answer:

Step 1 : Draw a line segment BC of length 7cm

Step 2 : Draw an angle of 45  

o

 from point B

Step 3 : From Ray AX cut off the line segment BD=1cm

Step 4 : Join C to D

Step 5 : Draw side bisector of DC

Step 6 : Extend side bisector of DC it intersect the Ray BX at point A

Step 7 : Join A to C, ABC is the required triangle.

On measuring, AB=6.1cm,AC=5.1cm
