Question

construct a tangent to a circle of radius 1.8 cm from a point on the concentratic circle of radius 2.8cm and measure its length. Also verify the measurement by actual calculation.​

Answer 1

Step-by-step explanation:

1.Draw a circle of radius 1.8 cm and centre as O.

2.Draw another circle of radius 2.8 cm and centre as O.

3.Mark point P on the larger circle.

4.Join PO.

5.Draw perpendicular bisector of PO which intersects PO at M.

6.Taking M as centre and MP as radius ,draw a circle which intersects the smaller circle at Q and R.
