Drawa circle with centre O and radius 5 cm. Draw two radii OA and OB so that they are inclined at an angle of 130 degree . At A and B construct tangents to the circle. Measure the angle between the tangents.
Answer :
We follow these steps :
Step 1 : Draw a circle with radius of 5 cm and center " O " .
Step 2 : Take any point " A " on circumference and join OA .
Step 3 : Now we draw 130 at point " O " with the help of protractor . As : B lies on circumference of circle , So OA and OB are radius of our circle
Step 4 : With any radius ( Less than half of OA and center " A " draw another arc that intersect our line OA at "D " with same radius and center " D " draw another arc that intersect our previous arc at " E " And again with same radius and center " E" draw another arc that intersect our main arc at " F " . Now with same radius and take center " E " and " F " we draw arcs that intersect at " G " .
Step 5 : Now with same radius and center " B " draw another arc that intersect our line OB at "H " with same radius and center " H " draw another arc that intersect our previous arc at " I " And again with same radius and center " I" draw another arc that intersect our main arc at " J " . Now with same radius and take center " I " and " J " we draw arcs that intersect at " K " .
Step 6 : Line AG and BK extend and meet at P .
Now we measure APB , we get
