Question

Draw a circle of radius 6 cm.From a point 10 cm away from its centre,
construct the pair of tangents to the circle and measure their lengths. with steps​

Answer 1

Answer:

Step1: Draw circle of radius 6cm with center A, mark point C at 10 cm from center

Step 2: find perpendicular bisector of AC

Step3: Take this point as center and draw a circle through A and C

Step4:Mark the point where this circle intersects our circle and draw tangents through C

Length of tangents = 8cm

AE is perpendicular to CE (tangent and radius relation)

In ΔACE

AC becomes hypotenuse

AC2 = CE2 + AE2

102 = CE2 + 62

CE2 = 100-36

CE2 = 64

CE = 8cm

Answer 2

1. draw a circle with radius 6 cm .
2. From the centre of the circle draw a line of 10 cm.
4. Then take the measure of drawan line as 8 cm and draw the interior Circle.
5. Draw arcs up and down
6. Then draw a perpendicular line to the arcs
7. Then draw the tangent to the circle
