Question

Let A and B be the centres of circles of equal radii of 2.5 cm of each. Draw them so that each of them passes through the centre of the other. Produce AB on the either side so as to meet the circles with centre A and centre B at point C and D respectively.
Measure CA, AB, BD, CB , AD and CD ​

Answer 1

Answer:

ca=5cm

ab=3cm

BD =7cm

cb =8cm

ad=2cm

cd=4cm

Answer 2

CA = 2.5 cm

AB = 2.5 cm

BD = 2.5 cm

AD = 5 cm

CD = 7.5 cm

Step-by-step explanation:

Let A and B be the centres of circles of equal radii of 2.5 cm of each.

Using compass draw two circle with radius 2.5 cm

• Blue circle with center A  ( Please find attachment )

• Green circle with center B (Please find attachment )

Produce AB on the either side so as to meet the circles with centre A and centre B at point C and D respectively.

C is point on blue circle.

D is point on green circle.

Now measure each length

CA is radius of blue circle, CA = 2.5 cm

AB is distance between center of two circle, AB = 2.5 cm

BD is radius of green circle, BD = 2.5 cm

AD is diameter of green circle, AD = 5 cm

CD is total length from one end to another end, CD = CA + AB + BD = 7.5 cm
