Question

Draw a tangent to the circle from the point B, having radius 3.6 cm and centre C.Point B is at a distance 7.2cm from the centre

Answer 1

Steps of construction:
1. Draw a circle of radius 3.6 cm with centre C. Take a point B such that CB = 7.2 cm.
2. Obtain the midpoint M of seg CB.
3. Draw a circle taking M as a centre and CM as the radius.
4. Let P and Q be the points of intersection of these two circles.
5. Draw rays BP and BQ which are the required tangents.
