Question

draw a circle of radius 5 cm and draw to tanget to the circle from distance of 8 cm outside from its centre​

Answer 1

Answer:

Draw ⨀(A,5 cm) and take point B in its exterior such that AB=8 cm.

To construct:

Through B, tangents are to be drawn to ⨀(A,5 cm).

Steps of construction:

1) Draw ⨀(A,5 cm) and take point B in its exterior such that AB=8cm.

2) Draw AB

3) Obtain the midpoint M of AB

by constructing its perpendicular bisector.

4) Draw ⨀(M,MA) intersecting ⨀(A,5 cm) at X and Y.

5) Draw BX and BY

Hence, BX and BY are the required tangents.

The length of tangents BX and BY

is 6.2 (approx)

i.e., BX=BY=6.2 cm (approx.)
