Question

construct circles with radius 2cm​

Answer 1

Answer:

Construct 2 circles centred at O and O

′

at a distance of 8 cm.

Circle O has radius 2 cm. O

′

has radius 4 cm.

Make another circle with radius 2+4=6 cm centred on the bigger circle.

Make a semicircle with O and O' being two end points of diameter. Let it cut the largest circle at N.

Join O

′

N and make a line parallel to O

′

N passing through O. Let it cut the circle at B.

Name the point where O

′

N cuts the 4cm circle as B.

AB is the required tangent.

On measuring, it comes out to be 5.3 cm
