Question

Draw a circle of radius 6cm. from a point 10cm away from its centre. Construct the
pair of tangents to the circle.
b) Draw a pair of tangents to a circle of radius 5cm. which angle between the radii is
120°
​

Answer 1

Answer:

FOR FIRST DIAGRAM

STEPS OF CONSTRUCTION

1. DRAW A CIRCLE WITH RAIDUS 6CM AND TAKE A POINT AT A DISTANCE OF 10CM OF THE CENTRE
2. JOIN THE POINT TO THE CENTRE OF CIRCLE
3. DRAW THE PERPENDICULAR BISECTOR OF THIS LINE
4. NOW KEEP THE COMPASS ON THE POINT OF DIVISION AND DRAW A CIRCLE
5. THE POINTS OF INTERSECTION ARE THE POINTS FOR TANGENTS

FOR SECOND DIAGRAM

STEPS OF CONSTRUCTION

1. DRAW A CIRCLE WITH RADIUS 5CM
2. WITH THE HELP OF PROTRACTOR DRAW AN ANGLE OF 120°
3. EXTENT THE ANGLE AND DRAW IT'S PERPENDICULARS
4. THESE ARE TANGENTS TO THE CIRCLE
