ke an angle of 120 with one another.Describe four circles, of different radii, touching bothof them. Two lines make an angle of 80 with one another.Describe a circle of radius J in. to touch both of them jalso of radius 1 in. Two lines make an angle of 60 with one another.Describe a circle touching… … Hence with centre DThis is the circle Bisect the angles at B and Cby the lines BD, CD. ThenBD contains the centres ofcircles touching- BA and BC;and CD contains the centresof circles touching CA and CB.Hence D is the centre of acircle which touches all threesides. DE, perpendicular toBC, is the…
