Question

draw a circle of radius 3 centimetre and construct a pair of tangents from a point 8 cm away from its centre​

Answer 1

Step-by-step explanation:

First : taking O as center draw a circle of radius 3 cm (such that OA = 3cm) .

Second : take a point 8 cm away from the centre. (means the OA= 3 cm and take a point of 5 cm and join it to the radius such that A' is joined to OA , you will get A'A= 5cm and A'O= 8cm) .

Third : draw the perpendicular bisector of the line A'O .

Fourth : after finding the center of the line , measure the radius of the first circle and draw another circle of the same radius .

Fifth : you will see that the second circle is intersecting the first circle .

Sixth : join the intersected points to the end point of the line A' and you will see that the tangents are drawn and when you will measure them they will be of same length .
